There is no such thing as a homozygous color-blind female.

Question

Quizplus · Accepted Answer

It is possible for females to be color-blind, but they can't be homozygous for the color-blindness gene as it is located on the X chromosome. Females have two X chromosomes, and if one of them carries a defective color-vision gene, the other X chromosome can compensate for it. Therefore, females with color blindness are always heterozygous, with one normal and one abnormal X chromosome.
