Final Answer :
B
Explanation :
A color-blind woman carries the recessive allele for color blindness on one of her X chromosomes. She will pass this allele on to all of her children, but whether or not they will be affected depends on the genotype of the father. If the father is also a carrier or affected by color blindness, the sons have a 50% chance of being affected and the daughters have a 50% chance of being carriers. If the father is not a carrier or affected, the sons will not be affected, but all the daughters will be carriers.
