Question: Why are males colorblind more often than females? Options:

A) females can mask it with one dominant allele on one of their X chromosomes

B) Males can mask it with one dominant allele on one of their X chromosomes

Since it's passed down on the X chromosome, red-green color blindness is more common in men. This is because: Males have only 1 X chromosome, from their mother. If that X chromosome has the gene for red-green color blindness (instead of a normal X chromosome), they will have red-green color blindness.
