1. White eyes is an X-linked recessive trait in Drosophila. Apure breeding red eyed female is mated to a white eyed male. Whatproportion of the progeny will be white eyed males? Round youranswer properly to 3 decimal digits.
2. A woman with normal blood clotting ability whose father was ahemophiliac and whose mother was normal with no family history ofhemophilia marries a man whose blood has normal clotting ability.Recall that hemophilia is an X-linked trait.
What is the probability that their first child will be a sonwith hemophilia? Round your answer properly to 3 decimaldigits.
3.
In Drosophila melanogaster, white eyes (w) is an X-linkedrecessive mutation. Normal eyes are red (W). At the autosomal wingshape locus, normal shaped wings (Vg) are dominant to vestigialwings (vg). The following cross was made:
XWXw vgvg x XWY Vgvg
What proportion of the progeny from this cross will be maleswith red eyes and normal wings? Write your as a numerical valuerounded properly to 4 decimal digits. Do not write the answer as afraction or percentage.
