  • This study was carried out to establish genetic understanding of three Sasang constitutions of Taeumin, Soeumin and Soyangin by Random Amplified Polymorphic DNA(RAPD) analysis. We have applied RAPD analysis to pooled DNA sample as a means to achieve rapid screening of large numbers of primers for their capacity to reveal constitutions-specific polymorphisms. From an initial 440 primers, 13 polymorphic primers between different constitutions were selected. Bandsharing(BS) and mean average percentage difference(MAPD) calculated within and between three constitutions using RAPD fingerprint data showed a higher degree of homogenity within than between the constitutions and indicated measurable divergence between three constitutions. The RAPD bandsharing(BS) values ranged from 0.71 to 0.73 between the three constitutions. The interconstitution divergence was narrower between Taeumin and Soeumin, than between the other paired constitution comparisons. The genetic distance between the three constitutions was measured by BS values. Genetic distance by RAPD analysis was 0.007 between Taeumin and Soeumin, and 0.014 between Soyang and the others. In conclusion, the genetic distance of Teaumin and Soumin was closer than that of Soyangin in the analysis of RAPD by using 440 primers.

  • Randomly Amplified Polymorphic DNA-Polymerase Chain Reaction (RAPD-PCR) analysis was carried out with a battery of 11 random decamer primers to study band frequency (BF), genetic identity index (I) and mean average percentage difference (MAPD) between Bhadawari and Murrah breeds of buffalo. The primers OPA04 and BG15 resolved a band of 460 bp, which was present only in animals of Bhadawari breed. Whereas, the primers OPA14, BG27 and BG28 produced Murrah specific fragments of sizes 730 bp and 1,230 bp, respectively. The estimate of genetic identity index was highest (0.845) with the primer OPA01 and the lowest (0.479) with the primer BG27. The genetic identity index pooled over the primers was 0.596${\pm}$0.037 between these two breeds. The highest MAPD estimate (53.9) between the two breeds was obtained with the primer BG27 and the lowest (14.3) with the primer OPA01. It might be concluded that the genetic identity index between these two breeds calculated on the basis of BF showed moderate level of genetic identity with the primers employed. MAPD calculated on the basis of uncommon bands also demonstrated lower to medium level of genetic difference between Bhadawari and Murrah breeds of buffalo.
