You are studying a population of giraffes. In this population, one gene (G) controls spot color in giraffes, which shows incomplete dominance. Individuals with white spots are homozygous gg, individuals with brown spots are homozygous GG, and heterozygotes have orange spots (Gg). You observe 25 white-spotted giraffes, 15 orange-spotted giraffes, and 22 brown-spotted giraffes. Calculate the observed allele frequencies, using p for the frequency of allele G, and the expected number of giraffes of each phenotype assuming Hardy-Weinberg Equilibrium (do not do the entire chi-square calculation!). For frequencies, report four positions after the decimal. For expected numbers, report two positions after the decimal. • p= • q = Expected number of orange-spotted = • Expected number of brown-spotted = Expected number of white-spotted =
