Inbreeding usa.

The average COI for purebred dogs is ~20%. Specific breeds can be higher or lower than this value. For some breeds, the average coefficient of inbreeding can approach or even pass 40%. Because these are average numbers, individual COI can vary. For example, some breeding lines may have more genetic diversity than others.

The slopes of these lines tell us exactly what this "cost-benefit" ratio is. For these breeds, those slopes are about 0.1, which means that an increase in inbreeding of 10% reduces litter size by about 1. If normal litter size is about 6, a COI of 30% - which is not uncommon in many breeds - would reduce the litter size by HALF.

This occurs across a wide range of traits and suggests a large number of deleterious alleles in the human genome. This has been predicted from the reduced early survival of offspring in first cousin marriages and from similar results in other organisms.1 ...Holstein Association USA is the world's largest dairy cattle breed organization, offering information services to all dairy producers.

Deep in the woods of Kentucky, a fiercely private family gave birth to blue-skinned children since the 1800s. The color of their skin was so shocking for normal people to see, that they chose to stay hidden away from the rest of society in their small community. Very few people knew they even existed, until today.
