outbreeding
outbreeding Mating between unrelated or distantly related individuals of a species. Outbreeding populations usually show more variation than inbreeding ones and have a greater potential for adapting to environmental changes. Outbreeding increases the number of heterozygous individuals, so disadvantageous recessive characteristics tend to be masked by dominant alleles.
