Question

a woman and her husband both have the same type of red-green color blindness. what percentage of sons and daughters will have the same red-green color blindness that their parents have? all of the children will have full-color site. the daughters will be carriers and the sons will have full color site. the daughters will be carriers and the sons will be color-blind. all of the children will be color blind.

Explanation:

Red-green color blindness is an X-linked recessive trait. A color-blind woman has two recessive alleles ($X^bX^b$), and a color-blind man has one recessive allele ($X^bY$). Daughters inherit one X from each parent ($X^b$ from mother, $X^b$ from father → $X^bX^b$, color-blind). Sons inherit X from mother ($X^b$) and Y from father → $X^bY$, color-blind. Thus all children are color-blind.

Answer:

All of the children will be color blind.
