Hj: Heterozygosity Level Within a Single Population

Description

From a set of allelefrequencies (from a single locus), the homozygosity is calculated by taking the sum of the squared allelefrequencies of all alleles. The heterozygosity is calculated by subtracting the homozygosity from 1 (Jost 2008, p. 4022).

Usage

Hj(p)

Arguments

p

a vector that contains the frequencies of all alleles for a single locus

Value

• The value returned, 'Hj', is the heterozygosity level for a single locus in a single population.

Details

The equation for the calculation of the heterozygosity is taken from Jost (2008, p. 4022).
