 In that case, the frequency of the \(A\) alleles moves from 0.9 to 0.92 across a single generation; there is some covariance between \(A\) types and reproduction. Inputting \(p = 0.5,\) and \(q = 0.5,\) the frequency change is greater, \(A\) types go from being half the population to frequency 0.56, and the covariance between offspring production and being an \(A\) type is correspondingly greater as well.
