Question

3) The most common form of color-blindness - red/green color-blindness - is an X-linked recessive trait affecting around 8% of the male population in the US. What proportion of females would you expect to have this trait?

Answer 1

Answer:

0.08, because for an X-linked trait the genotype frequencies among males are the same as the allele frequencies. Therefore, you would expect about q2 = 0.0064 (or 0.64%) of the female population to be affected and 2pq =0.147 (or 14.7%) of the female population to be carriers.
