If the fraction of the population with allele “A” at a given locus

is .7, and the fraction of the population with “a” at the locus is .3,

what will be the expected genotype frequencies in the F1?

Allele frequencies in P (parental generation):

A = .7 = p

a = .3 = q

Expected genotypes and their frequencies in F1:

AA = p2 = .49

aa = q2 = .09

Aa = 2pq = .42
