Genetic variability in domesticated and wild sheep based on blood protein characters.
1. The study examined genetic variation, as indicated by eight blood proteins of 539 animals from 11 genotypes (14 flocks) of domesticated sheep and three genotypes of wild sheep. 2. The polymorphic distribution among the animal populations presented a random pattern with wide variation. 3. Genetic variability both between and within populations was larger in domesticated sheep than in their wild relatives. 4. This increased genetic variability observed in domesticated sheep may have resulted from the process of domestication through accelerated genetic drift and promoted gene flow.
