Consider an autosomal locus with two alleles A1 and A2 at frequencies of 0.6 and 0.4 respectively. Each generation, A1 mutates to A2 at a rate of μ = 1 x 10-2 while A2 mutates to A1 at a rate of υ = 1 x 10-1) Assume that the population is infinitely large and no other evolutionary force is acting. The overall change in allelic frequency will be
