WebIsolation by distance (IBD) is a term used to refer to the accrual of local genetic variation under geographically limited dispersal. The IBD model is useful for determining the distribution of gene frequencies over a geographic region. Both dispersal variance and migration probabilities are variables in this model and both contribute to local genetic … http://rosenberglab.stanford.edu/papers/JakobssonEtAl2013-Genetics.pdf

WebFor the mean of all the loci, F ST = 0.048. Plugging that value into our equation, we get. Another approach to estimating gene flow involves using the average allele frequency of alleles unique to one population, across loci (p(1), or private alleles).In the equation below, a and b are constants equal to -0.505 and ó2.44, respectively, for sample sizes of 25: WebPairwise comparison of the genetic differentiation indexes (Fst) in the three groups showed the highest genetic differentiation between groups G and F (Fst=0.843), and the lowest between groups N and G (Fst=0.419). These results were in accord with the fact that there was greater genetic differentiation between than within subspecies.
