    Attention please.
    Pedigree no 3 can be both x-linked recessive or autosomal recessive..
    Very important to look again and again ..
    Both possibilities are applicable..

      Yes there is no any probability of x linked pass father to son but there is also a probability is that trait comes from mother...

    • @liteducks
      @liteducks 4 ปีที่แล้ว +21

      Because both father and mother are affected in the second generation, it is hard to discern whether the sons received the trait from mom or dad therefore allowing both autosomal recessive and x linked to be possible

    For the third question, from the diagram you can deduce that it's either x-linked recessive or autosomal recessive. It's unsure which one of the two is correct though, need more information.
    Additionally, for the fourth question, it doesn't have to be x-dominant, there're other inheritance patterns that fit that pattern...

  • @sitthuson
    @sitthuson 3 ปีที่แล้ว +23

    Practice pedigree #2 and #3, I see it as being "Autosomal R" & "X-linked recessive"...
    The rules about skipping generation and male to female ratio don't entirely eliminate x-linked. those rules are not always reliable.
    Care to explain?

  • @ericstevens7738
    @ericstevens7738 3 ปีที่แล้ว +1

    The right side of the third pedigree does not help elucidate autosomal recessive vs X-linked recessive. Granted, with two affected females in the same family from different bloodlines, it is probably more likely to be AR inheritance. We would need prevalence to weigh this speculation.
    However, using binomial statistics and the pedigree at hand, it is statistically speaking more likely X-linked recessive inheritance.
    Probability of getting the outcome of individuals 4,5,6,7 for AR = 0.09375
    Probability of getting the outcome of individuals 4,5,6,7 for XR = 0.37500
    Probability of getting the outcome of individuals 9,10,11,12 for AR = 0.140625
    Probability of getting the outcome of individuals 9,10,11,12 for XR = 0.187500
    This example was poor as it does not offer new students a concrete way to identify an inheritance pattern. Best of luck!

    In pedigree 3 in case of affected father do not pass traits to their son. But sons can be affected by affected female..
    But affected sons can come from affected mother, and affected female can come from affected father...
    Why not x linked recessive or dominant...

    Actually for that third question , mother can be a carrier right ? So theres also a chance that the male got affected like wise..if a carrier mother is croseed with unaffected male ,then theres of course a chance for male progeny getting affected right ?! So maybe it can be both autosomal recessive or X linked recessive .
