Molecular Genetic Variations in Indian Goats

In the present investigation, RAPD-PCR was employed to study genetic variations with in six breeds of Indian goat viz. Barbari, Black Bengal, Jamnapari, Marwari, Sirohi and Jhakrana breeds. Gene diversity is an appropriate measure of genetic variability with in a population. The polymorphism found within breeds varied between primers and breeds. Only small proportion (40.93%) of the total bands amplified from 10 selected primers were polymorphic. The information generated from the polymorphic patterns revealed by all the 10 primers was used to find out gene diversity using Pop Gene program (Population Genetic Analysis). The highest gene diversity was found in Black Bengal (0.2378 plus or minus 0.207) while the lowest was found in Sirohi (0.0992 plus or minus 0.174). Higher gene diversity might have been contributed by introduction of out breed population and random mating among individuals. The low genetic variability might be due to the fact that samples were collected from farm and there was more probability for selection rather than random mating thus accounting for low variation with in the breed.
