Inbreeding: Inbreeding refers to the mating of closely related animals of the same breed. Inbreeding promotes the accumulation of good genes while deleting unfavourable ones. Inbreeding, on the other side, reduces fertility and productivity. Inbreeding is an issue in human reproduction because it increases the risk of recessive gene disordersInbreeding coefficients (F ROH) were calculated by summing the total length of ROH for each individual and dividing by the autosomal genome length of 2281 Mb (McQuillan et al., 2008; Wade et al., 2009). The distribution of F ROH in North America was similar to the European and Australasian distribution, with median F ROH = 0.28 (Figure …

Inbreeding in Southern Appalachia has been a topic of discourse for both local color writers and academicians since the late 19th century, but only a few researchers have aspired to measure inbreeding or describe the genetic structure of Appalachian populations.

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.
