    • @jenniferdesrochers1640
      @jenniferdesrochers1640  4 ปีที่แล้ว +1

      Hi Jewel- are you asking about the sex-linked example? Genes can be linked to the Y-chromosome and pass from father to son. X-linked traits can only be passed from an affected or carrier mother to son because the Y must come from the father. Let me know if you have further questions!

    3:45 shouldn't it be Y-Linked? because it didn't skip a generation and it only showed up in male (specifically all of the sons), so why was it X-Linked?

    • @jdicey5552
      @jdicey5552 5 ปีที่แล้ว +4

      Mohammed Aljubury hemophilia is a recessive gene found on the X chromosome that affects the bloods ability to clot normally. As females have XX they will always end up with one functioning X chromosome that codes for correct blood clotting. Females with two dysfunctional X chromosomes result in a natural abortion. As males are XY they may end up with the recessive dysfunctional X chromosome.

    Fantastic video, thank you.
    I have one nit-picky comment. Instead of saying that the horizontal line indicates that people are married (1:08) I would have said "This horizontal line is called a marriage line, and it indicates that this couple had children together" because in reality parents are not always married to each other, and for the sake of studying biological inheritance, we don't need to make any assumptions.
    In any case, great explanation, thanks.

    Thanks for the great video!
    But AFAIK, the sex-linked diseases are always carried on the X chromosome so there is no male-to-male transmission as a son always inherits his X chromosome from his mother and the Y from his father so he isn’t affected by his father but the mother has to be at least a carrier for him to be affected. Hence, in the last problem the pedigree on the left can’t be a sex-linked disease since the mothers aren’t even carriers and the it’s male-to-male transmitted.

    What do you do with someone who you are not sure about? Some people on a pedigree could be Homozygous Dominant or Heterozygous, and you cannot tell by looking at the parents or offspring. Do you half-shade them or not?

  • @dschwamm
    @dschwamm 8 ปีที่แล้ว

    So when would we draw somebody as a carrier? I thought that the children who do not show the trait despite coming from a previous generation that is inflicted and then passes it on to a later generation would be a carrier but here they're drawn as simply not having having it at all? Or am I misconstruing the examples?
