Q1
A bird population has a beak-shape locus with alleles A and a. In a given year, allele frequencies are $p(A)=0.30$ and $q(a)=0.70$. The population is large, and mating is random with respect to beak shape. A severe drought occurs, and individuals with genotype aa have substantially lower survival to reproduction than individuals with AA or Aa. No migration is detected during the drought year. Assume allele frequencies are measured among the breeders that produce the next generation.
Which change in allele frequency is most likely after one generation?
