Effective population size is the size of … 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.
