Linked Genes
HTML-код
- Опубликовано: 14 авг 2024
- Paul Andersen explains how linked genes behave and how linked genes were discovered. He shows how linked genes would be reflected in a dihybrid cross using a fruit fly simulator. He uses chromosome-based punnett squares to explain why the frequency of recombination is less that 50%. The actual crosses discovered by Thomas Morgan and Alfred Sturtevant are included.

Never thought I'd be back at his channel in college, yet he still did a better job explaining this than my professor.
same! I'm in med school and I still come back for some of his videos
Instablaster.
How about you are getting rusty overtime... 😂
16:47 tell me why he slipped into a heavy Australian accent im scared
phoebe lawson LOL
xD
what the fuck LOL
Thank you!! I was stuck on this for 4 hours from my lecturer's video, and i got it from your video in 17 minutes. Plz replace my lecturer

I've never loved someone as much as I love you right now. This makes perfect sense, thank you.
I honestly couldn't ever have got into a medical school without you. Thank you so much you saved me so many times!
Wow! I finally understand what linked genes are. Thank you so much for this video. You saved me for this bio midterm tomorrow!
Honestly the only reason I'm doing alright in AP Bio. X"D Thanks so much for making these hard topics easier to understand!
I did this in high school too. I would sleep/not pay attention in class at all and the night before i took a bio test I looked at a few of your videos about 3 times each to fully capture everything you say and retain it and end up receiving an A on my test. Because of your help, I am able to bs my way out of biology :D
aahhhh I watched you during my high school days, and yet again I'm watching you for my med school exams again!!! One of the best!!!!!!
I have been watching your videos for half the semester now. Thank you so much. They are extremely helpful for my course!
Im a doctor myself and your videos are absolutely comprehensive and to the point.I learnt lot of things from you.Great work..
if you are a doctor, why are you learning about this topics?
I have to say that your videos are amazing!! You make things a lot easier to understand. You're well appreciated.
Okay so I literally just created a RUclips account a minute ago just to thank you Mr. Anderson for these videos. Everything makes sense now. You should be my professor. I came from the Galapagos Islands 2 years ago and it's kind of hard to understand all these terms and concepts but you make everything seem so simple and I actually understood every single thing you said. THANKS!
I DONT KNOW WHAT I WOULD DO WITHOUT YOU! thank you soo much.
instructions unclear, ordered many fruit flies from internet
U are ridiculous
@@erenyeager8080 yes. But the fruit flies in my house are more so, especially 3 years and 37289 gens later.

you are a brilliant teacher
Generations of Biology students were saved by this man. I suppose I am the latest generation to discover this video.
skip the first 11 minutes if you don't have enough time to watch the whole video
god thank you!
this guy is a life saver. I thank God I have found you early enough to help me through my biology class...I almost redrew from that class. Do you have tutorials on lab as well? Thanks a million times. I wish I had money to donate to support your course.
You are amazing. That helped me on my class very much. Greetings.
My teacher didn't even understand this. God bless you and i can't thank you enough!
beautifully explained. I'm in a 300 level genetics class at a major university and this is just spectacular. This is a very difficult concept to grasp just reading out of a textbook, and having a professor who simply reiterates what the text says doesn't help. Mr Anderson, You the man.
Awesome. I watch all your videos for every unit we study in school.
i have yet to watch one of these videos and come away disappointed. Every single time i will learn something new, or develop a better understanding. Thank you!
This makes perfect sense. THANKYOU SOO MUCH!! i have LITERALLY struggled to understand this for almost a year now.
eventually understood what linked genes actually are...here it goes.. my aha moment.thanks a bunch.

These lessons are great! I've always "known" genetics weren't as simple as the Mendelian theory we learn at high school. But I never found a more advanced explanation of genetics, and here it is! That's just great!
I understand better biology with your videos in English than in my native language when my croatian teacher explains it,thanks a lot Mr.Anderson :)
Mr. Anderson, you are the most amazing science teacher ever! :) Thank you! I love your videos!
I have never understood anything more clear than this! Everything now makes sense!
this dude explains incredibly well, wish i discovered his channel earlier!
You're great! It's like having my own tutor!
if you understand the basis of genetics, but just want to skip to the crossing over part- go to 9:00
This was so well explained!! Was so confused after reading the text but this makes perfect sense.
Wow this makes a lot more sense now--esp starting at around 14:40. Thank you!
your videos are really helpful.... please make more videos of topics regarding genetics
Thank you so much for making this topic easier to understand.
I really appreciate you lessons, their very succinct and effective. I use to solely use Khan Academy but now I have become a Bozemanbiology student.
a solid understanding of meiosis is critical to understanding linked genes
Thanks again, for such a great explanation about gene linkage. I'm just wonder if the lab that you were using to explain the fruit flies breeding is free or people must pay to have access???
That was an awesome video! Made me understand my biology class way better, thanks a lot!
You're an amazing teacher !!! I watched 10 other videos and I didn't understand the concept... I finally understand it :D
I wish you had a video about gene mapping
I watched this video 5 times!!
i wish you were my professor!
life would be much easier!!!
Thankyou so so much! This is going in a link to my teacher for sure. Y12 biology here I come!
This helped me get an A for the fruit fly lab. Thx bro and good vid, no need to waste time you know.
Dang!!!! When he stated at the beginning that i get it just thought to myself if he knew how much i was struggling with this concept he would not say that....but i had my "oh shoot i get it " moment .thanks alot for this video .for all your videos infact .
After days of study, I finally understand. Thank you.
Great explanation of the concept
thanku for this video...u r an amazing teachr..
Thank you! That was extremely helpful and easy to understand.
Loving your Genetics videos, thx
can you do a video on tri-hybrid crosses and how to calculate the recombination between it as well? That would help me heaps! or if anybody has any links as well!!
I have a test tomorrow and i think this just saved my score
Awesome Mr Anderson. Subbed and liked, helped me out for my lab report. Again, thanks.
this is the only time ever i have actually understood linked genes. i can't sleep and wanted to watch a video on gene linkage to put me to sleep but it was so interesting and genuinely educational it did the exact opposite. the aha moment is real!!!
Thanks again Mr. Anderson!! Great videos Ive learned so much !!!
Daaammn. Best one I've come through so far👆
Thanks mr.andersen. Your videos really help
Why go to school when you can watch something as awesome as this from the comfort of your bed..!!
Thanks this helped me a loooottttt. The diagram at 14:25 cleared everything up.
Extremely well made video, thanks.
Thank you :) We're just learning about this in my class so great timing haha.
Amazing....Really helped me
Great video! Very good instructor. Thank you!!!
Aha!
Well, I"ve gone through a bunch of videos on this topic, and no one really explained this good!
It's very helpful! I can really understand it now. The only thing is that in my textbook it says that the recombination happens in 36% of oocytes ( if you were to have 100 female gametes and 100 men ones, so that you get 100 zygotes) and my question is how you calculate this percentage?
You did an AWESOME JOB! Thanks so much for sharing this :)
Shout out to VCE Bio students cramming
Ayyyyyy
What's VCE mean???
Excellent video!
Thank you so much, I finally understand linked genes!
the lower the percentage for recombinant genes, the nearer/shorter they are in terms of map units on the gene map.
How I wish provision of education in our schools would be something of this kind...! But big big thanks to you...
Thanks for sharing these video clips
Thank you, Mr. Andersen, it helped a lot. Idk how ill pass this AP bio.
at 15 minutes I had my "OOOOHHH" moment
I've always hated genetics. Thanks for the video, it helps!
You are so lovely. Thank you for sharing this with all of us
Damn eight years ago...
What were your hypotheses for the chi square? I am working on a lab and need an example of dependent assortment for this exact topic!! I do not know how to explain why we use the parent!! Help!
i have no idea, i've understood biology pretty well up until genetics, it seems everyone can get it, except for me .____.''
thanks for the video, it cleared some things up!
Omg thank you! Light bulb moment happened exactly at 15:36 😂 while in lecture, even after three lectures and reading that the text book😒 not even a glimpse at a light bulb moment 🤦🏽♀️
Awesome explanations!!!!!! Thank you!!
is there any advantage in using the bl vy thing, rather than just BbVv ????
5:00 how do you know it's recessive??
Was confused by this too. Had to watch it a couple times. He noticed that both male and female were wild type in wings and color from the first cross. He then said that the mutations are recessive and by mutations he was referring to black color and vestigial wings. So the wild type is the dominant.
you're my hero and always will be ^.^ !!
This was amazing! Thank you!
it's very helpful. thanks!!
Great video man!
Amazing explanations!
Just.....thank you. Great work.
Wish you were there in our school! :/ Thanks! :)
It was very helpful. Thank you.
wow excellent explanation, bravo
Why less than 50% means genes are linked? is this theory suitable for all gene recombination?
Because if they were not linked, they would end up together 50% of the time anyway, through independent assortment of alleles to gametes. AND for genes greater than 50 centimorgans apart, it isnt possible to tell if they reside on the same chromosome.
Thank you Paul!
Extremely Helpful! Thanks!!
thank you very much for your effort
I'm going to have nightmares, about fruit flies when this semester is over; I just know it. Thanks for your help.
YES THAT WAS VERY HELPFUL
Great video
i want to use the fruit fly lab but i need a course code
+Damone Henry use a guest acct it doesnt matter
