WebInbreeding is the production of offspring from the mating or breeding of individuals or organisms that are closely related genetically. [2] By analogy, the term is used in human reproduction, but more commonly refers to the genetic disorders and other consequences that may arise from expression of deleterious or recessive traits resulting from ... Whilst inbreeding depression has been found to occur in almost all sufficiently studied species, some taxa, most notably some angiosperms, appear to suffer lower fitness costs than others in inbred populations. Three mechanisms appear to be responsible for this: purging, differences in ploidy, and selection for heterozygosity. It must be cautioned that some studies failing to show an absence of inbreeding depression in certain species can arise from small sample sizes or wher…

The more inbred a dog is, the higher the chance that the same version of a gene has been inherited from both dam and sire – both for desirable and undesirable traits. This could increase the chances of a dog being at risk for both known and unknown inherited disorders ...
