Genetic Differentiation Among Goats Using Randomly Amplified Polymorphic DNA (RAPD) Markers

Anbarasan, K., Sharma, A.K., Singh, R.K., Deb, S.M. and Sharma, D. 2001. Genetic differentiation among goats using randomly amplified polymorphic DNA (RAPD) markers. J. Appl. Anim. Res., 20: 83-88. To develop population specific markers using randomly amplified polymorphic DNA-ploymerase chain reaction (RAPD-PCR) in meat (Black Bengal and Non-descript Rohilkhand Local), milk (Barbari) and pashmina (Chegu) producing goats, a total of 35 random sequence decamer primers were tested. Nine primers generated polymorphism in one or more goat populations. Out of 117 bands scored, 46 (39%) were observed to be polymorphic. One of the primers (OPM-18) was found effective in differentiating the Pashmina (Chegu) from meat or milk type of goats. While the primer OPI-05 generated one band which might be specific for meat type goats i.e. Black Bengal and Non-descript (Local). However, population specificity and sequence homology for these bands need further investigation by hybridization, cloning and sequencing experiments.
