Consider the gene that determines Rh blood type in human beings. This gene has two alleles (D, d) with D being dominant to d. Suppose that in a certain island population of 1000 individuals there are 250 individuals that have the genotype DD, 500 individuals that are heterozygotes, and 250 have the genotype dd. What are the genotype and allele frequencies in this population?
