Color Blindness Problem Set

Problem 3: Barbara's genotype

We have determined that Audrei is homozygous recessive for the red-green color blind allele and that her father is hemizygous with a recessive allele. What is the mother's genotype? Remember that Audrei's mother does not have a color perception defect.

A.	homozygous for the dominant, normal vision allele
B.	heterozygous carrier of the red-green color blind allele
C.	homozygous recessive for the red-green color blind allele
