Unformatted text preview: state where C goes to fixation. How do we get to the "best" condition? Consider the effects of population structure: Bantu people establish local breeding groups of small effective population size. This necessarily will bring on some inbreeding which serves to increase homozygotes and decrease heterozygotes. Some CC genotypes will be produced by the chance effects of inbreeding and now the "best" genotype is present in the population and selection can "see" it so the frequency of the C allele increases, and the population would go to fixation for C. The highest fitness state could not be reached by selection alone; Drift can affect the outcome of selection . This has been conceptualized as an Adaptive landscape:...
