- Once you have a background in pedigree conventions, this video should provide you with the tools to evaluate a pedigree to determine if a given trait could be autosomal dominant, autosomal recessive, or X-linked recessive.
Why did RUclips never promote or invest in their science part of the community? We need these type of videos so badly.
There is some GREAT content out there now. Check Crash Course or Bozeman Science for biology stuff.
Who else is studying for their genetics final?
ha me
The grind never stops
🙋🏻♂️
Biology 😔
U have a final that's just on genetics ? You're so lucky
Flat out amazing. I understand pedigree analysis in a way I hadn't before. Continue to pump out these comprehensive yet easy to understand videos!
I'm taking my biology final soon and this video just saved my life! This was so helpful I've never been able to understand pedigrees until now
+Micaela Dempsey I'm glad I could help!

Your Better than my Teacher
+Alex Murphy Thank you.
Alex Murphy same
you're*
This video was extremely helpful! I had no idea what I was doing before and now I do. Thank you!
Clear, clean, and right to the point, wish there were more professors like that. I've only had a few who are right to the point in a very straight and organize fashion! Thank you!
Thanks so much for the kind words! I find that making a video cuts out all the nonsense and just gets right to the point. When I'm actually teaching, there is some mumbling and stumbling involved...
Was searching everywhere for this. Finally found it! Helped a lot on my previous tests. Way to go on the editing of the video!
I'm thrilled to help! Thanks.
THANK U SO MUCH. I ACUALLY LEARNED BETTER THAN MY TEACHER. KEEP UP THE GOOD WORK.
THIS IS THE MOST CLEAR EXPLANATION THAT I GOT
Thanks to your help, I can finally solve Pedigree Problems.
This video stands out form the other videos on pedigree simply because of the fact that every characteristic of each particular trait was specified.
This significantly helps in solving pedigree questions of higher difficulty.
Thank you very much SiouxScience !
Thanks for taking the time to comment. I appreciate the kind words.
thank you so much... this helped alot... I had an assignment to submit and I had no idea about this pedigree... ur video was very helpful
Dang this video really helped me understand pedigrees! Thank you so much, every single explanation was on point and very detailed!
I try... the problem is when you make a little mistake and don't want to go through all the work to fix it... Thanks!
Thank you so much, I was so sad that I couldn't wrap my head around this concept...but this video made it a whole lot clearer!
Thanks, I really appreciate the kind words!
by far the most relevant video I have found on this related to the class I am taking. Thanks!
+Justin C Thank you! I'm glad I could help.
An hour and 45 minute lecture condensed into 12 minutes and understanding the pedigree more? Another blessing! Thank you!
Thanks for taking the time to comment! Makes the hours spent making some of the suckers worth it. I'm glad I could help!
Extremely informative! Thank you for simplifying inheritance and pedigrees.
Thank you! I'm glad I could help out.
I have a big test on pedigrees tomorrow, and this video has made it so much easier to understand!
+Krista Jordan I'm glad I could help. Good luck!
Really cool vid. Explanations are really clear and consistent. Love your work.
+Lexi Mary Thank you! I appreciate you taking the time to comment.
I find making notes on this really helps to follow this video. Thanx. Very helpful.
I'm glad I could help!
Thank you so much this is by far the best video on YT about this topic, well at least the basics of it
Thanks so much for the kind words!
Helped a LOT on half of my take home final!
+wrkin90044 Good! I'm glad I could help!
After missing two days of biology (Im a sophomore in highschool) I was completely CLUELESS on how to solve pedigrees. After watching this I understand them like no other. Thanks to you, I got 100% on my pedigree quiz. This video was great help.
If only more of my students would bother to watch the videos.... I'm glad to have been helpful.
If any of the guys still have doubt then can send me question. Will clear it to you ! I AM FROM INDIA 😇
me too :)
This was fantastic, thanks so much. Really helped me out for the MCAT
Glad I could help! Hope it went well!
i literally cannot thank you enough. this was so helpful, and I'm one to learn slower and take more time to understand
My pleasure! Making a video you can pause... I need to make things as clear and concise as I can. I'm glad to help!
This video is perfect! I finally understand those tricky pedigree problems, thank you!!!
+Annelise Fernandez I'm glad I could help!
The explanation was amazing. Thank you very much for this wonderful work.
+Jabeen Thaz Thank you!
I am preparing for NEET and it's very helpful ......thank u for this video sir
Wow. Thank you soo much! You really helped me with differencing these three gene inheritance.
My pleasure!
Genetics heaven!! Thank you for helping me understand
I'm happy I could help! You're welcome.
Thank you! This was very helpful!
I watched many and this is the best one yet thx man.
Sorry for the delay… summer break. Thanks so much for the kind words!
wish there were more videos on this, your explanation was beautiful
This is some tricky stuff! Thank you for taking the time to comment - I appreciate it.
I personally found this to be helpful:
1. Determine whether its's dominant or recessive? How? Dominant is present in every generation while recessive skips generations
2. Determine whether it is autosomal or sex-linked? How? Autosomal affects both genders equally while sex-linked affects mostly one gender.
More Notes:
Wish You Good Luck.
I love the problem solving involved, to be honest. Then again, I'm a biology major and science teacher... Thanks for the TL:DW.
unfortunate thing is that I could like the video only once.really helpful. thank u sooo much BiologyMonk.
It takes a ton of time to go through and make this sort of video, so I really appreciate the feedback! Thank you.
Thank you for this video. It is very well done and explained. You give time and tips to work out a pedigree. :)
You're welcome!
Thank you so much! this helped me a lot
I'm glad to help! You're welcome.
I have watched so many videos about pedigrees and I only understand this one thanks!
Thanks so much!
I'm in med school and this video just saved my life. thanks haha
I must of looked at like 3-4 other videos on how to solve this. looked at andrew douch, did not get it. I looked at yours and i got it, thanks a lot. helps to dumb it down, thx

My pleasure!
This is awesome! thank you so much!!
I'm glad I could help!
thank you!!! this was a real life saver!
I'm glad I could help!
great video! with tay sachs though can you assume the mother would be heterozygous? Couldn't she be homozygous dominant?
Thank you so much, you are saving my life before exam :]
You're welcome! Good luck!
Thanks! This is really good! It definitely helped me out for my examination!

Bless you biology monk!
Thank you!
made it soo easy...nice one!
Thank you!
great explanation. thanks alot Prof
Thank you! I hope it was helpful.
Great video! THanks
+Don't Frown Thank you!
Minor correction on 1:25 - stated "HYPOcholesterolemia... or genetic HIGH cholesterol." Should be "hypercholesterolemia" for genetic high cholesterol. Nevertheless, great presentation. Thanks very much for taking time in putting this together! :)
+TrueCourse Whoops! Thanks for the heads up. I'll take a look at that and try to get things fixed!
Awesome content sir. Thank you so much.
Thank you and you're welcome - glad I could help!
Thanks really appreciate your work
So nice of you. Thanks!
Excellent!!
Glad you like it!
They say not all heroes wear capes.
Thank you BiologyMonk.
...and in this case I think they'd be right. I really appreciate the comment!
Thanks for this
This was explained really thoroughly and I'm solving pedigrees no problem, thank you! My professor is impressed :)
I'm glad I could help!
I'm not sure but wouldn't autosomal dominant diseases with reduced penetrance be able to skip generations?
+Danny H I just tried to cover some basics. You're right - there are plenty of other possibilities out there.
Thank you so Much for that video bcoz it that make easy pedigree understanding
+Surendra Chauhan You're welcome! I'm glad I could help.
Thank you so so much!!!!:)
This helped sooo much, Thank you
I'm thrilled I could help!
Very informative!
Thank you!
really useful, In 8th grade taking 9th grade stuff helps on my test, thanks
+ImaJew I'm glad I could help. You're welcome.
What confuses me is that at times I feel as if a pedigree could be both autosomal or x-linked. As in, sometimes the pedigree doesn’t have something to differentiate the two. Like both ways it makes sense, so idk. Anyways, I think recall you saying that these problems aren’t meant for you to prove something but rather disprove something. Overall, great video, I understood and learned a lot :)
Sometimes it COULD be more than one type of inheritance. You try to eliminate options, but sometimes can't. Key things to look for would be males disproportionately having a trait over females.
Best teacher ever....
Thanks!
Thank you. Very helpful
I'm glad I could help! You're welcome!

thank you so much for this!!!
You're welcome!
Excellent.
Thank you!
well done but sometimes there is a probleme they really don't give us any clue .. for me the main problem is to make the difference between a auttosomal recessive or an X linked recessive that is really heard ..
What you USUALLY find with X linked recessive traits (male pattern baldness, red-green color blindness, hemophelia) is that males get them. You're right though - sometimes it can be numerous types of inheritance... and then there are polygenic traits, X linked dominant traits... endless other complexities.
Where is X-linked Dominant? Anyway great vid
Why the hell didn't I search for you, sooner? Thank God for your videos
Thanks so much for the kind words and watching.
Thank you very much
+Kumari Mani You're welcome!
This is extremely helpful, thank you so much! This can be quite a confusing topic. I have one small question, though: aren't there X-linked dominant conditions?
This is tricky stuff! There are all sorts of other modes of inheritance.... these are just some of the basics.
Most people with dominant diseases have one copy of the allele (they're heterozygous). A dad would have a 0% chance of passing on an X linked dominant trait to his son, 100% chance to his daughter. A mom would have a 50% chance of passing on this trait to her daughters or sons. Good luck!
Ok, thank you very much! I just wanted to make sure it was a real thing, because you didn't mention it in the video. Great video, by the way! I learned a lot!
Really helpful
Thanks 🙏
Glad I could help! Thanks for watching.
How can i controle bee mating ?
Great video, but one thing. You just did one example for how to tell if a pedigree is x linked or autosomal and recessive or dominant. That example was perfect, because it had an affected mother with an unaffected son and a generation skipped. This showed that it was obviously recessive and autosomal, but I wish you had shown scenarios that did not have this.
I get what you're saying... the issue is that can confuse people even more. Thanks!
Good video!
Thanks so much!
So far very helpful. But for the question that ends at 8:15----- what's probability that II-1 and II-2 would have a 5th child w/ this disorder? I get that the heteros crossed gives 1/4 aa. But does it not matter that it's specifically asking for 5th child? How would/wouldn't answer differ if it asked for 4th child?
It does not change the probability that they will have an affected child. If two parents have 3 daughters, then what are the chances their next kid will be a female. The answer is 50%. It's in the wording of the question you see? If the question was what are the odds a couple will have 6 daughters and no sons, the answer would be different.
