The hemoglobin B gene (Hb) has a common allele A that is found at a frequency 0.89 and a rare allele T that is found at a frequency of 0.11 in a population from Nigeria. The T allele encodes the sickling form of hemoglobin, HbS.
In a sample of 600 people from this population, how many individuals would you expect to be affected by sickle cell anemia?

14) whenever diploid populations are in hardy-weinberg equilibrium at a particular locus a) the allele's frequency should not change from one generation to the next, but its representation in homozygous and heterozygous genotypes may change. b) natural selection, gene flow, and genetic drift are acting equally to change an allele's frequency. c) this means that, at this locus, two alleles are present in equal proportions. d) the population itself is not evolving, but individuals within the population may be evolving.
