Question

Quizplus · Accepted Answer

Red-green color blindness is actually linked to the X chromosome, not the Y chromosome. Since males have only one X chromosome (XY), a single defective gene on their X chromosome will result in color blindness. Women have two X chromosomes (XX), so a defective gene on one of their X chromosomes can often be compensated for by a normal gene on the other, making them less likely to exhibit color blindness.
