Inbreeding has what effect on homozygosity
When two closely related organisms mate, their offspring have a higher level of homozygosity: in other words, an increased chance that the offspring will receive identical alleles from their mother and father. In contrast, heterozygosity occurs when the offspring receives different alleles.
