Abstract
Mitochondrial DNA as a Marker for Genetic Diversity and Evolution
The formulation of the modern breed concept during mid-1800s has caused remarkable changes in the livestock sector: largescale production expanded and its application to breeding and husbandry practices led to the formation of well-defined breeds, exposed to intense anthropogenic selection. As a consequence, farmers progressively substituted the less productive, locally adapted, native breeds with highly productive cosmopolitan breeds and progressively abandoned marginal areas.
