Definition: Dissimilar alleles which are present at one or more loci, so the individual is heterozygous at those loci.
Context: Most studies of the loss of genetic variation caused by bottlenecks in population size have used heterozygosity as a measure of genetic variation.
Expression: Loss of heterozygosity (LOH)
