There are three genes in the gene pool for blood, A, B, and O. Two of these three are present in a person's blood: A and B dominate O, whereas A and B are codominant. This gives the following possibilities: Genotype Phenotype AAtype A bloodAOtype A bloodABtype AB bloodBOtype B bloodBBtype B bloodOOtype O bloodLet p, q, and r represent the frequencies of the genes A, B, and O in the blood gene pool. Suppose a certain population has 40% type A, 37% type B, and 23% type O. Construct a Punnett square and find (p + q + r) 2 to answer, what percent of the population has each genotype.
A. AA = 16%, AO = 18.4%, AB = 29.6%, BO = 19.02%, BB = 12.69%, OO = 4.29% B. AA = 16%, AO = 19.4%, AB = 30.6%, BO = 15.02%, BB = 13.69%, OO = 3.29% C. AA = 18%, AO = 19.4%, AB = 30.6%, BO = 16.02%, BB = 12.69%, OO = 3.29% D. AA = 17%, AO = 20.4%, AB = 30.6%, BO = 16.02%, BB = 12.69%, OO = 3.29% E. AA = 16%, AO = 18.4%, AB = 29.6%, BO = 17.02%, BB = 13.69%, OO = 5.29%
