Inbreeding usa

INBREEDING occurs when mates are more closely related than expected if chosen at random in the population. Most cultures have taboos against close inbreeding and most nonhuman animals appear to avoid it, ostensibly as an adaptation to prevent its deleterious effects (Pusey and Wolf 1996).Inbred offspring tend to have higher rates of congenital disorders and lower survival rates and fertility.

Links to PubMed are also available for Selected References.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. The positive correlation between inbreeding coefficients and distance from Africa was eliminated if heterozygosity was controlled, indicating that the increase in inbreeding coefficient is a manifestation of the same reduction of ancestral population size outward from Africa that contributes to decreasing heterozygosity.

With such a small gene pool, inbreeding was inevitable. By the 1800s it was said that every royal in Europe was mentally ill. And certainly that every royal family was an inbred family. Still, while all royals carried dangerous genes, most were born relatively healthy. It was only now and then that a prince or princess was born sick.
