Description

Compute the expected F_ST in a finite island model.

Usage

1
	expected.fst(total.number.of.demes,effective.size,migration.rate,mutation.rate)

Arguments

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

Details

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.

Value

Expected F_ST in a finite island model of population structure, with equal sized demes and isotropic migration across demes

## This is to get the expected level of population differentiation in an island model with 100 demes,
## each of size 1000, that exchange migrants at a rate of 0.001. The mutation rate is assumed to be 0.000001.

expected.fst(total.number.of.demes = 100,effective.size = 1000,migration.rate = 0.001,mutation.rate = 0.000001)
