Consider a population with two loci (A, B) each with two alleles (A,a and B, b). Which of the following represent expected frequencies for particular haplotypes, if the frequency of allele A = 0.5 and the frequency of allele B = 0.7, and alleles are combined at random across the two loci?


ab = 0.25 and aB = 0.25


AA = 0.25 and Ab = 0.3


AB = 0.35 and bb = 0.09


AB = 0.7 and Ab = 0.125


Ab = 0.15 and aB= 0.35
