Genetic diversity of horses and chickens – a review

The diversity of farm animals is the result domestication species through a long process migration, selection, adaptation, and other natural events. This needs to be conserved demographic characteristics, recording production environment, effective data management. In this process, presented based on molecular biology tracing becomes very important because discovery so many breeds livestock found today, especially horses chickens. Data records or morphological characteristics difficult use in an effort determine hierarchy chickens, population studies that are mostly carried out studies. Through studies, variations genetic chickens will easier understand. believed several events, most notably red jungle fowl (Gallus gallus) may also involve Gallus sonneratii possibly lafayettii. Horses were domesticated broad areas Eurasia steppe. It thought mares underwent times, but few stallions contributed formation horses.Keywords: Genetic Diversity, Horses, Chickens, Domestication, Livestock database
