Inbred genetics
WebThe basic genetic consequence of inbreeding is to promote what is technically known as homozygosity. This means there is an increase in the frequency of pairing of similar genes. Accompanying this increase, there must be a decrease in the frequency of pairing of dissimilar genes. This is called a decrease in heterozygosity.

Inbreeding is the process of mating genetically similar organisms. In humans, it's associated with consanguinity and incest, in which close relatives have sexual relationships and children. Inbreeding violates modern social norms but is fairly common in animals and plants.

Early studies argued that 85–90% of the genetic variation is found within individuals residing in the same populations within continents (intra-continental populations) and only an additional 10–15% is found between populations of different ... WebThere are genetic consequences when forming breeds (inbreeding for specific traits). The most obvious one is the loss of genetic diversity. With inbreeding comes the unintended consequence of an increase in disease-producing alleles (variant form of a gene).During breed formation, the priority and focus is selection for breed traits such as stature and …
