Inbreeding in Rats. Inbreeding is the practice of mating closely related individuals. In rats, this can occur when siblings or other close relatives are bred together. While inbreeding can sometimes lead to desirable traits, such as increased uniformity in appearance or behavior, it also carries significant risks.The population was divided into ten ten-year birth cohorts (1846-1945) and 22 geographic subdivisions in order to assess temporal and spatial variation in inbreeding. The average inbreeding coefficient for this population is 0.000 106. The average within-groups random kinship coefficient is 0.000 312, reflecting consanguinity avoidance.Inbreeding Depression. A phenomenon known as inbreeding depression —the reduced survival and fertility of offspring of related individuals—occurs in both plants and animals, showing that variation for heritable fitness traits occurs within populations.

These three statements are worth examining. First, "the CDCB and USDA are actively monitoring any potential new genetic defects that may affect our cattle population.". For the record, inbreeding does not cause genetic defects. Mutations cause genetic defects. Inbreeding creates the opportunity for the discovery of mutations (both new and ...Inbreeding is the mating of those very close relatives. In this context, inbred matings are so close they would be considered incestuous among people (parent/offspring, siblings, etc.) To a geneticist, however, both are "inbreeding" because you are in both cases breeding related individuals with each other.Inbreeding. Inbreeding is the mating of related animals. This simply means they have one or more ancestor in common; the closer the relationship between two animals, the greater the amount of inbreeding in the resulting progeny. (Bob Guest).

The short answer is that inbreeding is a measure of the probability of identity by descent of two alleles at a given locus in a given individual. This concise definition itself is the problem.

Progeny of related individuals often are at selective disadvantages within populations (Ralls et al. 1988; Crnokrak and Roff 1999; Keller and Waller 2002; but see Ballou 1997), leading to the evolution of strategies to minimize inbreeding in the wild (Pusey and Wolf 1996).A 2015 study revealed little variation in body height among Egyptian Pharaohs compared to the general population, signaling the presence of extensive inbreeding among the ancient Egyptian royalty.
