Quizplus · Accepted Answer

Colorblindness is an X-linked recessive trait, meaning that males (who have only one X chromosome) are more likely to be colorblind than females (who have two X chromosomes). In this case, the mother is not a carrier of the colorblindness allele (XᶜXᶜ), and the father is colorblind (XᶜY). Therefore, none of their children can be colorblind.
