Charles and Emma Darwin.The number of colored breed bulls in the United States is currently at an extremely low level, and this number will only increase with a market incentive or additional breed association involvement. Increased education and extension could be beneficial to increase knowledge about inbreeding levels, use of genomics and genetic improvement, and ...

Inbreeding commonly leads to inbreeding depression, the reduced fitness of individuals due to deleterious recessive (or partially recessive) mutations exposed in the homozygous state [8,9]. In livestock, for every 1% increase in (pedigree-estimated) inbreeding, there is an estimated 0.13% decrease in the mean selected trait value [ 10 ].Background. Inbreeding plays a central role in the evolution of many plant and animal populations, affecting for example effective population size [], the speed of adaptation [], or the accumulation of deleterious mutations and the resulting inbreeding depression [27, 33].Much attention so far has focused on self-fertilization, the most extreme form of inbreeding, which is widespread in plant ...INBREEDING depression, the reduction in fitness observed in the progeny of genetically related individuals, plays a key role in population biology, affecting processes as diverse as the management of livestock and endangered wild species (Keller and Waller 2002; Koenig and Simianer 2006), the evolution of mating systems (), and the dispersal strategies (Motro 1991; Gandon 1999).

Comparison with data taken from the published literature suggests that the levels of cousin marriage observed are consistent with a secular decline during the late nineteenth and twentieth centuries.As a result, strategies to minimise inbreeding are widely applied in conservation contexts 19. However, few studies of inbreeding also consider generations in captivity: as inbreeding is often positively correlated with time in captivity, other mechanisms of fitness change over time may be confounded with inbreeding 20.

The aim of most animal-breeding schemes is to maximise rates of true genetic gain (Δ G true) at acceptable rates of true inbreeding (Δ F true).Δ G true is calculated as the increase in true breeding value (TBV) averaged across animals in a breeding population.

Ocelots (Leopardus pardalis) in the United States currently exhibit low levels of genetic diversity. One hypothesis for this observation is that habitat fragmentation, resulting from human induced changes in the landscape during the 20th century, created island populations with highly reduced gene flow and increased genetic drift and inbreeding. In an effort to investigate this, we used a ...
