Inbreeding and genetic diversity
WebAug 1, 2011 · Breeding practices, inbreeding and inherited disorders Breeding and selection practices may have an impact on genetic structure of the breed. They also affect the evolution of genetic diversity within a given breed, as well as risks linked to the dissemination of genetic disorders. WebInbreeding depression occurs because of a quirk of natural selection and genetics. As natural selection acts on a population, it weeds out genes that have disadvantageous effects, but it can only weed out these genes if they are actually expressed in an individual. For dominant gene versions, that’s no problem.
