Question

Quizplus · Accepted Answer

Dichromatism is more common in males than in females due to its genetic basis, which is linked to the X chromosome. Since males have only one X chromosome, a defect in the gene responsible for color vision on that chromosome will result in dichromatism. Females have two X chromosomes, so a defect in one can often be compensated for by the other, making them less likely to be dichromats.
