Question

Quizplus · Accepted Answer

Visual color deficiency is least commonly found in females due to the fact that the genes responsible for the most common forms of color vision deficiency are located on the X chromosome. Since females have two X chromosomes, a defective gene on one of them can often be compensated for by a normal gene on the other, whereas males, with only one X chromosome, are more likely to express color vision deficiencies if they inherit a defective gene.
