Why does a single X chromosome that carries the allele for red/green color blindness?

Why does a single X chromosome that carries the allele for red/green color blindness?

X-linked red-color blindness is a recessive trait. Since males have only one X-chromosome, if this chromosome has the red-green color blind allele, the males will have the color perception defect. Females have 2 X-chromosomes. Both X-chromosomes must carry the mutant allele for the females to be color blind.

Why does a single X chromosome that carries the allele for red/green color blindness cause males to be color blind but doesn’t cause females to be color blind?

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. Females have 2 X chromosomes, one from their mother and one from their father.
