WebH1: Inbreeding Depression. Usually, when there is no genetic diversity in a given population of animals, certain problems will start to arise. We shall explore these problems and their implications. What is Inbreeding Depression? Inbreeding depression is defined as the reduction in biological fitness of a given population as a result of inbreeding. WebInbreeding depression is widespread across plant and animal kingdoms and may arise from the exposure of deleterious alleles and/or loss of overdominant alleles resulting from increased homozygosity, but these genetic models cannot fully explain the phenomenon. Here, we report epigenetic links to inbreeding depression in maize.

WebInbreeding is the mating of individuals related by ancestry. It is measured as the probability that two alleles at a locus are identical by descent (F). Inbreeding increases homozygosity and exposes rare alleles. When parents of an individual share one or more common ancestors (i.e. are related), the individual is inbred.
