Punnett Squares and Sex-Linked Traits
Explore inheritance when carried on the X chromosome with the Amoeba Sisters! This video has a handout here:
This video focuses on how to do general Punnett square problems that involve traits on the sex chromosomes (X and Y chromosomes). We do want to point out though that when it comes to biological sex- it can be influenced by more than just sex chromosomes X and Y. For example, the SRY gene, plays a major role in human biological sex determination. While this video only focuses on solving sex-linked trait problems in a Punnett square, here are some further reading suggestions to learn about the SRY gene and its role in biological sex.

This really help
bruh they teach me more than my teacher does
Such a great channel!
I knew I find a video from you guys, thanks you save my test
I use capital N for normal / healthy & n for defect / bad news allele. That way its the same for red-green color blindness, hemophilia and muscular dystrophy. That way i don’t break the “rule” or etiquette of using Capital for dominance…love your work <3
A big help before examination
Yall stoopid
why is the recessive gene (h) the one that gives the child the trait and not the dominant one (H)?
Yeah, it always freaks out my teachers when I say I have protanomaly colorblindness…. And I'm a girl. I mean my dad has colorblindness and my mom is a carrier (well we knew after I was in kindergarten that she was carrier). I know it's rare but it does happen. They always say that they've never had a girl student with colorblindness. I've met a few women with colorblindness, so I don't know how they've never had one before.
When you get to the Punnett Square part, you go way too fast and only give one example. Isn't that supposed to be the focus of this video?
I’m homeschooled and have to do these videos but I don’t find them horrible and boring I find it fun
poor romanov's
Very Helpful!
Why can't the male with hemophilia be a carrier even if he is affected? Won't his mutated allele show in the punnet square?
Why are you soo cute 😍😍😂😂😂 don't stop making videos like this okay I need you😊
I love your videos so much, not only you explain it well but also it's funny.
Your videos are brief and straightforward. Thank you for making them!
I did not understand why the purple boy is not a carrier, he has x h and y
A potato was used for the audio recording!
Great content though!
thank you so much! AMOEBA SISTERS
5:16 Morty has hemophilia!!!
The videos of amoeba sisters are always informative and enjoyableee❤️
Can you make linked gene video please?
Is color-blindess also recessive?
Sex chromosomes are Wiggly Gigglys.
Is dis the same of sex linke genes?
Omg!!My science Teacher let me watch this i luv it!! ITS FUNNy sOMetimEs but you did really smart,genius and cool i like the way you are 🙂 welp,im not gay ok? Ima a girl.😄😄😄
Cant believe i only found you gals the day before my last bio exam – hot damn its time to cram
Thank god for this video, I'm doing an online course right now for Biology 12 and this topic was only 1 paragraph
I’m in 7th grade and this video will really help me with my test tomorrow
omgggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggg
