calc.intersp.het: Calculate Interspecific Heterozygosity
In introgress: methods for analyzing introgression between divergent lineages

Description Usage Arguments Details Value Author(s) See Also Examples

This function calculates interspecific heterozygosity of individuals from a matrix of allele counts.

1	calc.intersp.het(introgress.data=NULL)

introgress.data

a list produced by prepare.data or a matrix with allele counts.

This function calculates an admixed individual's interspecific heterozygosity (i.e. the proportion of the individual's genome with alleles inherited from both parental populations) based on allele counts. This function should only be used for co-dominant markers.

A numerical vector with an estimate of interspecific heterozygosity for each individual.

## load simulated data
## markers have fixed differences, with
## alleles coded as 'P1' and 'P2'
