WebBased on Wright’s fixation index, at generation 59, substantial genetic differences were established between lines. The effective population size was 39 in LWS and 33 in HWS. The effective number of founders was 17 and 15, effective number of ancestors were 12 and 8, and genome equivalents were 2.5 and 1.9 in LWS and HWS, respectively. 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.
