Abstract

In this study polymorphism on beta-lg and bGH genes in Holstein and Brown Swiss cattle reared in Bursa region were investigated by using HaeIII and MspI restriction enzymes. While frequencies of A and B allelles of beta-lg were found 0.3430 and 0.6570 in Brown Swiss population, they were found as 0.5480 and 0.4520 in Holstein population, respectively. MspI (+) allelle of bGH was predominat in both Brown Swiss and Holstein populations with frequency of 0.9623 and 0.8158, respectively. Both of two populations were found in Hardy-Weinberg equilibrium for both of the two loci investigated.
