Question 132866: Genetic problem, sex-linked problems.
I need help solving this problem:
A man and his wife both have normal color vision, but a daughter has red-green color blindness, a sex-linked recessive trait. The man sues his wife for divorce on grounds of infidelity. Can genetics prove evidence supporting his case?
Answer by vleith(2983)   (Show Source):
You can put this solution on YOUR website! can he sue? Sure. But he may well lose.
Color blindness is a recessive trait. The only way to have a child born that way is if both parent carry the gene. Assuming neither parent is color blind, both could still be carrying the gene and not know it.
So, if the father is tested and does not have the gene at all, he has a case. But, he may well have the gene as a recessive trait. In that case, he is 'half of the reason'.
