F s t = v a r ( p) p ¯. , where p ¯ = 1 J ∑ j = 1 J p j and v a r ( p) = 1 J ∑ j = 0 J ( p − p ¯) 2 is the variance in frequencies among populations. This original formulation is valid only for a bi-allelic locus. Nei (1973) generalizes this definition to loci that have more than two alleles.

WebSelective sweep. In genetics, a selective sweep is the process through which a new beneficial mutation that increases its frequency and becomes fixed (i.e., reaches a frequency of 1) in the population leads to the reduction or elimination of genetic variation among nucleotide sequences that are near the mutation.
