total.number.of.demes |
total number of demes in the island model |
effective.size |
effective population size of each deme |
migration.rate |
rate of migration among demes |
mutation.rate |
mutation rate. The model assumes a 2-alleles model of mutations |
Computes the expected F_ST in a finite island model of population structure, with equal sized demes and isotropic migration across demes. The mutation model is a 2-alleles model. This function is based upon eq.(6) in Rousset (1997), adapted for haploids.

## each of size 1000, that exchange migrants at a rate of 0.001. The mutation rate is assumed to be 0.000001.
