If a female that is a carrier for color-blindness has a child with a male that has normal vision, what percentage of their children may be color blind?

The answer is 50%, since the mother is the only a carrier.  Color-blindness is inherited as an X-linked recessive trait. A color blind (recessive trait) woman will pass the allele to all her children. The most common autosomal abnormality present in people is an extra chromosome 21.
