Hey @2minuteclassroom I've recently found your channel and it is very useful for study. It explains things quickly and simply so that I can study efficiently. I find it just as helpful if not more than channels like crash course and Bozeman science. Thanks
This video really woke me up I was feeling really tired but then my teacher assigned this to google classroom. I watched it all the way through and took lots of notes, thanks for the lesson 2 minute classroom
Thank you for the video. My son was having a hard time understanding the Punnet square so I started looking for a video and came across your video. I learned and then explained to my son how to make Punnet square. Short and precise.
I was stressed out because i am currently sick (with strep throat) and my teacher announced on Google Classroom that we have a test on Punnett Squares on Friday, so i decided to watch a video about them and this was the first result. I copied down the example of the Punnet Square and did the worksheet she posted and this helped me so much! The arrows were definitely helpful in figuring out where the genotypes go! Thank you again! (Also she isnt the best teacher so i didnt really understand this even though shes been teaching it for a week! You helped me understand it in 2 minutes!)
thank you for getting to the point really fast, about to take a test and all of the videos are 30 min long, yours on the other hand got right to the point, thank you!
Thank you so much for this. I'm learning about this for biology right now and was a little stumped. Makes way more sense now. Going to watch some more complex examples so I can truly master it!
This was really confusing for me at first cus I couldn't get the difference in GG, Gg. but you helped me alot to learn it and I bot this video from my teacher. your a big help thank you.
Thank you so much for this video! I haven't been listening at all in clas lol and my teacher just posted an assignment about this. Great video, it helped me a lot.
You have to calculate each porcent like GG = 25% means 1 and the two different letters add 50% which means 50% = 2 and the last is the gg= 25% which is only 1 all together is 1:2:1 because each square is equal 25% which means 100% total
Thanks for the help. I have a test tomorrow and you helped me out to understand the punnet square so thank you, the video was short and precise nice vid. thnx
Thank you for this useful information, i really appreciate this data about how the genetic codes work and these punnett square information you are giving us, we are blessed to be in your presence for 2 minutes i really appreciate how well you teach, thank you and amen
In your studies, this information will be given to you or you'll be given the information you need to derive it. In the real world, much testing is done to determine dominance. And it is often much more complex than what is portrayed in the classroom.
Hey, 2 Minute Classroom, thanks for the amazing video! I just wish to ask in the second example, which color represents either the dominant or recessive traits (or does this question apply at all)? Also, is having a lowercase letter as the first letter of the genotype, the reason for the recessive trait resulting in 25%?
Hey, so I’m having a final test tomorrow and I don’t understand something This may seem dumb but how do I know if the green eyes are dominant and the blue eyes are recessive?
I have the bio staar later so I'm just going over things I kinda forgot, this was an amazing video! It was super quick and got straight to the point, nice!
In the first example the Mother has Green eyes (Heterozygous allele), telling us the big 'G' (dominant allele) of the mother is an allelle for Green eyes (G).If the recessive allele 'g' for the mother in this same example is for a different eye color for example Brown eyes (g), and the father has both recessive allele for blue eyes . What phenotype of eye colour is expected in the off-spring with the 50% chance of acquiring homozygous recessive allele from both parents (that is, Which phenotype becomes dominant in a case of two different recessive alleles acquired from the parent, The recessive Brown eye colour from mother or the recessive blue colour from the father?).
Thanks for your questions. There is no possibility of brown eyes in the first example, only green and blue. If there is a big G present, then the individual will have green eyes, whether it's GG or Gg does not matter. The only way to get blue eyes in this example is to have both recessive alleles, gg. Does that make sense? It is possible to have multiple alleles for a given gene in which case there will always be a hierarchy of dominance. search "multiple alleles" on google to learn more. I'll probably make a video on it sometime down the road.
The same way we've outlined in this video. since square (S) is dominant, any combination with S will be square and the only combination that can produce round is ss. Does that help?
If you say Gg is for Green eyes dominant and gg is for blue eyes recessive... While putting the information on the punnet square you will have Gg for the first row, follow by Gg , then gg and gg Giving us the ratio of 2:2 Percentage of 50% 50% ...
In homozygous, the allele from each parent is the same. In heterozygous, the allele from each parent is different (one dominant and one recessive in this video)
thanks this helped but I was wondering on your video Dominant Alleles vs Recessive Alleles it said that the dominant trait is always capital why here its Gg why not GG and how do I know?
This is the hardest topic in biology all the other topics weren't too bad but this one I struggle to understand it What happens when you have a mutation I don't understand how some people understand it quickly better brain maybe?
Great question. In some cases, there is a hierarchy to the alleles, so one of the recissives may mask the other. In other cases, the recisives will blend their train equally.

100% the best channel for study, gets straight to the point, no bullshit. Better than crash course
Thank you ❤️❤️❤️
Yes, sirrrrrr!!!!
my teacher made me watch this:(

@@2MCteee ty
just remember that each of those squares are equivalent to 25%!

Like twice the outcomes of a coin.
Thank you!! I’ve been struggling with these and your comment helped me a lot!!!
Thank you
i had to sit in class trying to understand what the teacher was saying abt punnet squares for 2 weeks and u teached me it in 2 minutes!!
This video really woke me up I was feeling really tired but then my teacher assigned this to google classroom. I watched it all the way through and took lots of notes, thanks for the lesson 2 minute classroom
You're welcome.
This is the first time anyone has said my video woke them up. So thank you for that.
This video is great it gets directly to the point, with no bs. Learned more from this than I did in an hour of biology, lowkey saved my grade
So glad it helped.
Same
I don’t know what I would’ve done without this video it was explained way better than my teachers
This actually helped me so much, considering I have a test coming up in a few days 😭 Thank you! Best channel for studying

Y’all, this actually rlly worked- I rlly recommend- my grades are horrible for bio/science, but I assure you, this actually helped so much
Short, simple, easy to understand, and re-playable. Great vid bro
Thank you for this! I’m studying for a test coming up tomorrow and this helped me understand how the Punnett square works!
Awesome! You are welcome.

So happy to hear it.
This has to be the best guide ever. I now fully understand it and now im not sitting in class looking stupid. Thank you so much :D
Thank you so much for this video! I haven't been listening at all in clas lol and my teacher just posted an assignment about this. Great video, it helped me a lot.
Glad it was helpful!
I never thought I'd understand how to do these!! thank you so much :))
When biology and probability interact, the result is genetics.
Well said.
this man is better than all science teachers
Thanks a lot i have my exam tomorrow and i wanted to practice the punnett square but u explained it so beautifully i dont even have to look at it now
2:22 I dont understand how to find out the pheneotypic ratio, could anyone help?
There is 1 GG, 2 Gg, 1 gg. Ratio 1:2:1
You have to calculate each porcent like GG = 25% means 1 and the two different letters add 50% which means 50% = 2 and the last is the gg= 25% which is only 1 all together is 1:2:1 because each square is equal 25% which means 100% total

Thank you you just solved my science quiz TMMR and I didjnt get it until I saw this, I’ll watch more of your vids your really good
I've been struggling doing this on quizzes and now im finally ready for the exam
Sweet!
Thank you very much you are way more accurate of teaching than my own teacher in the Philippines. 👌👌👍👍💖💖
Love you man, always clutching up with these videos, wish I had you as a teacher.
Hey, 2 Minute Classroom, thanks for the amazing video! I just wish to ask in the second example, which color represents either the dominant or recessive traits (or does this question apply at all)? Also, is having a lowercase letter as the first letter of the genotype, the reason for the recessive trait resulting in 25%?
Really helpful this pandemic forces online learning and these really help me to understand the concept
I'm glad it helped. Stay safe.
Omg Tyy so much I have an test on this topic tmr
I just missed 1 Biology class and i needed this before the test thanks….
Thank you. I now understand Punnet Square hehehe hope to learn more.🎉❤
Hey, so I’m having a final test tomorrow and I don’t understand something
This may seem dumb but how do I know if the green eyes are dominant and the blue eyes are recessive?
You should be given that information.
i got a test tmrw too and literally asking the same question to myself🤣
Saving me for my bio finals
I have the bio staar later so I'm just going over things I kinda forgot, this was an amazing video! It was super quick and got straight to the point, nice!
My teacher gave me this for work I dont understand maths but I actually got this !!
Yay!
thank you so so much sis you literally saved my life
TYSMMM!!! I have a test tomorrow and had no idea how to figure out the ratio and things. BUT TYYYSMMM FOR HELPPING
I really like doing my homework by understanding it not like just search the answer online thanks for teaching me man.. I'll give you a like 👍
I found this video very helpful for my studying. Thank you.
brief but precise. thank u.
That's my goal.
In the first example the Mother has Green eyes (Heterozygous allele), telling us the big 'G' (dominant allele) of the mother is an allelle for Green eyes (G).If the recessive allele 'g' for the mother in this same example is for a different eye color for example Brown eyes (g), and the father has both recessive allele for blue eyes . What phenotype of eye colour is expected in the off-spring with the 50% chance of acquiring homozygous recessive allele from both parents (that is, Which phenotype becomes dominant in a case of two different recessive alleles acquired from the parent, The recessive Brown eye colour from mother or the recessive blue colour from the father?).
Thanks for your questions. There is no possibility of brown eyes in the first example, only green and blue. If there is a big G present, then the individual will have green eyes, whether it's GG or Gg does not matter. The only way to get blue eyes in this example is to have both recessive alleles, gg. Does that make sense?
It is possible to have multiple alleles for a given gene in which case there will always be a hierarchy of dominance. search "multiple alleles" on google to learn more. I'll probably make a video on it sometime down the road.
Nice vid
Ive a doubt, why is Gg taken and why not GG??
I needed this so bad😂😂 this is all my science teacher had to say😭 thanks a lot🤞🏽
This is so helpful for my test tomorrow thank u
Thank you so much for this, I’ll show my son this to get a better understanding. 🥳🎉💐
Tysm, this was very helpful I really didn’t understand stand these, as you explained how to do these I found it easier than I thought
I can understand this better than my teacher
I'm having a problem with putting the letters in the punnett square like is the G first the one or is it okay if I switch letters??
how would we do one where is says (its a spongebob theme) Square is dominant to round and it says use S for square and s for round?
The same way we've outlined in this video. since square (S) is dominant, any combination with S will be square and the only combination that can produce round is ss.
Does that help?
@@2MC thanks!
Love it the colour code makes it easy to understand
Your videos were extremely helpful during the pandemic. Thank you!
What program are you using to create these videos?
I use VideoScribe to create my videos.
I'm glad they've helped you.
If you say Gg is for Green eyes dominant and gg is for blue eyes recessive...
While putting the information on the punnet square you will have Gg for the first row, follow by Gg , then gg and gg
Giving us the ratio of 2:2
Percentage of
50%
50%
...
Correct.
ive learned more here than my teacher this whole year
Thank you so much!, im ready for my test tomorrow on this
2 min video thought me something that a teacher woudnt in a couple of hours
Came in clutch lol. Btw thanks for this, it helped me out a lot
I'm here for last minute saves 💪
Thank you so much this helped me understand my online classes-
Glad it helped!
I watch you from France... On youtube we havent got explications as good as yours So i cant understand all but it helps me thanks :D
Well I'm glad you can get something out of my videos.
Tysm for the video I was struggling trying to do this in class and it's very easy after all!
this has helped as i was assigned this for my studying :)
thanks alot now i can go to the exam with no pressure
How is the heterozygous different from the homozygous?
In homozygous, the allele from each parent is the same. In heterozygous, the allele from each parent is different (one dominant and one recessive in this video)
@@2MC Thank you so much!!!
is it okay if we place the G where we want?
Thank you so muchhh, I love this tutorial,thanks for helping me study
You're very welcome!
U r really making good content 🤗🤗😄😄😄 within 2 min and really beneficial
Whats the difference between FF and Ff?
THANK YOU SOOO MUCH YOU MADE IT SOO SIMPLE
Thank you. This is easier than I thought
Thank you so much, this helped me a lot. Have a quiz on this next period and I feel fully prepared after watching this.
If there is no trait?how can you identify the phenotype?
Does the maternal are always be with a dominant allele?
Or maybe you have a video which will tell, how to find out : which one is dominant which album is recessive
great video man i owe u one but how did u get the ratio and percentage
thanks this helped but I was wondering on your video Dominant Alleles vs Recessive Alleles it said that the dominant trait is always capital why here its Gg why not GG and how do I know?
and how did u get the ratio?
thank you so much i have test next weak and didnt understand a thing about punet squares but know i understand
Thanks I got a test tomorrow 1st period
Best of luck!
Omg wait a video that is actually useful thanks kind sir
Glad you liked it
Excellent video very well explained, thanks it's been a while since I studied this!
Thank you!
This is the hardest topic in biology all the other topics weren't too bad but this one I struggle to understand it
What happens when you have a mutation
I don't understand how some people understand it quickly better brain maybe?
Thank you. I'm awaiting the presentation a complicated punnet square.Thank you
I haven't started working in that video yet, but I am certain it will be beneficial for many.
2 Minute Classroom thank you. the way you're explaining makes me learn so awaiting the video. Thanks ever so much.
phenotype doesn't go in the box?
thanks to this video i understand my lesson
but what if you have lets say TTxtt? how do u get the results for them? help will be really nice! loved the video learned alot.
How can you tell that it is dominant or recessive?
Thanks man🙏
What does it mean if you two people have the same genetic makeup ?
Generally means that are identical twins. Unless you are referring a specific section of their genes that are identical.
Please tell me how many numbers are in π
All of them
Can you do a video on bond angles in chemistry please?
I definitely should. I need to get some good chemistry videos up. Thanks for the suggestion.
Excellent explanation. Thank you
How did you determine Gg as material and gg for paternal?
i dont think it really matters its just to show how it works
What about brown eys
What is it's 100% smth
Thanks for explaining my teacher assigned this video but it's helpful.
How about when both are recessive and no dominant genes
Great question. In some cases, there is a hierarchy to the alleles, so one of the recissives may mask the other. In other cases, the recisives will blend their train equally.
You make it for me very easy thank you bro
You are welcome!
