5. Cheetahs are big cats that roam the African savanna. Because of a mass extinction event 12,000 years ago, cheetah populations have very low genetic
variation.
a. How will this lack of genetic variation affect natural selection and the survival of a
cheetah population if the environment changed dramatically?
b. What is the most likely source of new genetic variation in a cheetah population?

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.
