WebInbreeding reduces survival and reproduction (i.e. it causes inbreeding depression), and thereby increases extinction risk. Inbreeding depression is due to increased homozygosity for harmful alleles and at loci exhibiting heterozygote advantage. WebDec 22, 2014 · Inbreeding increases homozygosity that results inbreeding depression, with negative effects that we can loosely refer to as "loss of vigor". Heterosis - hybrid vigor - is the reversal of the loss of vigor that defines inbreeding depression as a result of an increase in genetic heterozygosity.
