Our analysis of data from 135,572 Thoroughbred horses revealed a strong negative relationship (all P < 0.001, Fig. 1) between Wright ...This reduction is manifested in many ways. The most obvious effects of inbreeding are poorer reproductive efficiency including higher mortality rates, lower growth rates and a higher frequency of hereditary abnormalities. This has been shown by numerous studies with cattle, horses, sheep, swine and laboratory animals.

This is known as Inbreeding Depression and refers to a population decrease due to lack of healthy mates. The problem can have a simple solution. Adders in Sweden were isolated due to farms and suffered an increase in stillbirths and offspring suffering from congenital defects. New adders were added and their population flourished.

Inbreeding is a topic we don't often hear much about, and for good reason. But it has an interesting history. Some of the most powerful people from history h...Figure 1 illustrates the effect of inbreeding depression on percent open and percent dead at birth. An increase in the inbreeding coefficient results in a change in the performance for the two traits. This change in the percent of open cows as a result of inbreeding would be in addition to the usual per-centage open in a non-inbred population.

Results. We experimentally manipulated the diet (control versus low food) of inbred and outbred juvenile Eastern mosquitofish (Gambusia holbrooki) for three weeks (days 7-28) to test whether experiencing a presumably stressful environment early in life influences their subsequent growth and adult phenotypes.The control diet was a standard laboratory food regime, while fish on the low food diet ...The effects of inbreeding and purging on racing performance.

Introduction. Inbreeding refers to the production of offspring by the mating of related individuals, often via consanguinity—intra-familial unions of individuals related as second cousins or closer.

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).
