MLH {inbreedR}

Calculate multilocus heterozygosity (MLH)

Description

MLH is defined as the total number of heterozygous loci in an individual divided by the number of loci typed in the focal individual. An MLH of 0.5 thus means that 50 percent of an indiviudals loci are heterozygous.

Usage

MLH(genotypes)

Arguments

genotypes

data.frame with individuals in rows and loci in columns, containing genotypes coded as 0 (homozygote), 1 (heterozygote) and NA (missing)

Value

Vector of individual multilocus heterozygosities
