Explore inheritance when carried on the X chromosome with the Amoeba Sisters! 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.
