WebQuestion: If a population that would otherwise have an effective size of 200 has a level of inbreeding of F=0.2, what will be its actual effective size? (Hints: Say what effective population size means, describe how inbreeding affects heterozygosity, and then calculate a number.) Please explain how to solve this! WebWe can calculate how much genetic drift we expect to find in a population if we know the effective population size. The expected variance in the frequency of an allele (call this frequency p) subject to genetic drift is: Var …
