In terms of consanguineous relationships in the United States, some rural areas in states like West Virginia, Kentucky, and Arkansas have been associated with higher rates of intermarriage between close …The negative consequences of inbreeding have led animal biologists to assume that mate choice is generally biased against relatives. However, inbreeding avoidance is highly variable and by no means the rule across animal taxa. Even when inbreeding is costly, there are numerous examples of animals failing to avoid inbreeding or even preferring to mate with close kin. We argue that selective and ...The dangers of inbreeding or having children with a close relative weren't completely understood for a long time. The biggest problem with inbreeding is that when close relatives choose to mate, it results in homozygosity, which can increase their offspring's chances of being affected by deleterious recessive traits for all kinds of physical and cognitive disabilities, including ailments like ...
