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

The frequencies of two allele’s p and q for a gene locus in a population at Hardy-Weinberg equilibrium are 0.6 and 0.4, respectively. After a few generations of inbreeding, the heterozygote frequency was found to be 0.10, The inbreeding coefficient in this case is
