Do Deer Inbreed? Emily Kantner Apr 9, 2023. Spend much time at deer camp, and you'll probably hear a hunter blame wonky antlers, piebald coloration, and other genetic abnormalities on inbreeding. But the science says incestuous mating usually isn't to blame, and inbreeding is a nearly insignificant concern for whitetail hunters.

Consanguinity in Arab Populations. Socio-cultural factors, such as maintenance of family structure and property, ease of marital arrangements, better relations with in-laws, and financial advantages relating to dowry seem to play a crucial role in the preference of consanguinity in Arab populations [].Consanguineous marriages are generally thought to be more stable than marriages between non ...Kentucky!

Background Achieving rapid genetic progress while maintaining adequate genetic diversity is one of the main challenges facing the dairy industry. The increase in inbreeding can be used to monitor the loss of genetic diversity. Inbreeding tends to increase the proportion of homozygous loci, some of which cause homozygosity of recessive alleles that results in reduced performance. This ...
