Question

when a male with heamophilia XhY is crossed with female carrier of both heamophilia and colourblindness XcXh then what is the probability that female offspring will turn out to be phenotypically normal?​

Answer 1

Answer:

50%

Explanation:

XhY  x    XcXh   parents

XhXc    XhXh   XcY   XhY       Offsprings

so 1 daughter will be carrier for both hemophilia and colorblindness who will be phenotypically normal.

another daughter is haemophilic

1 son is haemophilic and another is colorblind

so out of 2 daughters 1 is normal hence 50% daughters will be phenotypically normal

hope it helps
