The coefficient of inbreeding is the probability of inheriting two copies of the same allele from an ancestor that occurs on both sides of the pedigree. These alleles are "identical by descent". The inbreeding coefficient is also the fraction of all of the genes of an animal that are homozygous (two copies of the same allele).

2. White tigers in captivity exist due to inbreeding. The white tiger is a result of a rare genetic mutation and the most efficient way to breed them is by using two tigers who have the recessive genes needed to produce offspring with a white coat. In captive breeding facilities these two individuals are often related, making inbreeding common.

Animal breeding - Artificial, Natural, Hybrid: Crossbreeding involves the mating of animals from two breeds.

Yorkshires have acceptable rates of gain in muscle mass and produce large litters, and Durocs are very ...In the United States, selective chicken breeding began accelerating in the 1960s. In the 1950s, an average chicken used for their meat—known in the industry as a "broiler" chicken—weighed about two pounds at 56 days old. Today, after decades of selective breeding, an individual bird of the same breed and age weighs in at more than nine pounds.Inbreeding is defined as mating between related individuals. It is also called consanguinity, meaning "mixing of the blood." Although some plants successfully self-fertilize (the most extreme case of inbreeding), biological mechanisms are in place in many organisms, from fungi to humans, to encourage cross-fertilization.Therefore inbreeding-derived negative consequences in the gene pool have brought concern.
