    This video has been updated! Visit ruclips.net/video/dN9SZHO6Wjg/видео.html
    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, we have added some further reading suggestions in the description regarding the SRY gene if interested!
    Also, we want to add, when we first made this video back in 2015, there was a point in the video where we said "gender," but we should have said "sex." A person kindly educated us back then about how these two words are defined differently, and we corrected this mistake.

Where no matter if you are studying engineering vs psychology you'll still need to take other classes as base understanding for the more specific classes you'll take later on.

      Yes, there are 2 of them, both of them talked in their biology review video.

    Your contents are always the best. I would prefer watching your videos than listening to our biology teacher.😂

    The video at about 4:00 says the guy with the recessive h gene cannot be a carrier. Why wouldn't he be a carrier?
