Inbreeding in the united states

In United States maize production, OPVs were abandoned in the early 1920s due to the difficulty of improving their quantitative traits (i.e., yield) as well as lack of uniformity (Duvick, 1999). However, it is unknown whether OPVs could outperform hybrids today if they had been as intensively developed (Duvick, 1999). OPV breeding could be ...

A possible explanation for the association in North America between inbreeding and number of race starts, but not with ever racing, may be the practice of training and racing at the same race track. Horses that perform high intensity 'work' exercise ...In the previous generation 1·12% of the marriages were between first cousins, and the estimate of mean inbreeding was 0·0007. Comparison with data taken from the published literature suggests that the levels of cousin marriage observed are consistent with a secular decline during the late nineteenth and twentieth centuries.Inbreeding causes the number of direct ancestors in a pedigree to differ from 2 t (where t is the number of generations in the past). For example, the progeny of first cousin matings have six, rather than eight, great-grandparents. As inbreeding affects the number of ancestors in a pedigree, it results in modified organismal coalescence times.

Slave breeding was long a part of slavery. As in other slave countries, its purpose was to make more slaves. Slave breeding became more important in the United States the 19th century when the Atlantic slave trade ended. As with other commodities, scarcity caused the price of slaves to rise, so more slaves meant more money for their owners. [1]With data on the effects of inbreeding in wild populations scarce, some zoologists questioned its importance (or even its existence) in natural populations 1, 2, 3.
