WebDec 9, 2024 · Inbreeding often happens when populations are small and there are few options for mating. Inbred individuals are usually less healthy. Inbreeding Depression: ↑ Inbred individuals share ancestors and are more likely to have identical copies of genes. WebHowever, if a family of carriers begins to interbreed with each other, this will dramatically increase the likelihood of two carriers mating and eventually producing diseased offspring, a phenomenon known as inbreeding depression. Changes in allele frequencies that we identify in a population can shed light on how it is evolving.
