Question

Quizplus · Accepted Answer

A color-blind female is not expected because the woman would have to inherit the color-blindness allele from both her father (who is color blind) and her mother (who is not), which is highly unlikely since the allele is X-linked recessive. If she did inherit the allele from both parents, she would not be able to see any colors at all (complete color blindness), which is a very rare condition.
