Red/green colorblindness is an X-linked recessive disorder, meaning that the gene responsible for it is located on the X chromosome. Females have two X chromosomes so even if they have the recessive allele, they have another X chromosome with the normal allele which can counteract the effect. Males, on the other hand, have only one X chromosome and if it carries the recessive allele, they will express that condition. As the Y chromosome does not carry the corresponding gene that might counteract the effect of the specific allele associated with the condition, males are more susceptible to red/green colorblindness. The other options do not accurately explain the increased susceptibility of males to red/green colorblindness.
