Consider a locus with two alleles - B and b. B is dominant,while b is recessive. There is no mutation. B has a selectiveadvantage relative to b, so that the fitnesses of the threegenotypes are BB = 1, Bb = 1, and bb = 1-s. In this case, s = 0.50,so that bb homozygotes have 50% fitness of heterozygotes and BBhomozygotes. If the population has the following genotypic countsprior to selection of BB = 500, Bb = 250, and bb = 250, what is thefrequency of B after one generation with selection? Please giveyour answer to two decimal places.
Note: the answer is not .39 or .625
