Inbreeding in the us.

Inbreeding is the mating of those very close relatives. In this context, inbred matings are so close they would be considered incestuous among people (parent/offspring, siblings, etc.) To a geneticist, however, both are "inbreeding" because you are in both cases breeding related individuals with each other.1. Introduction. Mating with relatives (inbreeding) can result in offspring with reduced survival and fertility, a phenomenon known as inbreeding depression [ 1 ].

Inbreeding makes it more likely for this to happen. Scientists use a genomic method called ROH (Runs Of Homozygosity) to study how much inbreeding there is in a population. Studies have shown that the Amish have extremely long ROH, which means they have a lot of inbreeding.The diversity in our DNA helps protect us from many different diseases. Via wpclipart. Now I think you can see why inbreeding can cause problems here. When inbreeding happens and two closely related people have children, these children will probably have less diversity in their DNA. Which means they have fewer types of MHC alleles (or fewer keys).

After many generations of inbreeding, the offspring will be almost genetically identical, and will produce identical offspring. When this happens, an organism is described as inbred or purebred.
