A) 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?

B) In a randomly mating lab population of fruitflies, 4% of the
flies have black bodies (encoded by the autosomal recessive
b allele), and 96% have brown bodies (the wild type,
encoded by the B allele). Assuming the population is in
HWE, what are the allele frequencies of the B and b? What are the
genotype frequencies of B/B and B/b genotypes?
