WebOne can calculate Fst from molecular markers, and if an estimate of effective population size is available, migration can be estimated from the following relation: Fst Å 1/(4Nem + 1). By rearranging the formula and plugging in trial values you can see that low values for m result in high values for Fst, and high values of m give low values of Fst. 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!
