HINFI POLYMORPHISM OF K-CASEIN AND PIT1 GENES IN ROMANIAN SIMMENTAL CATTLE

VIORICA COŞIER, A. VLAIC, IOANA GABOREANU

Abstract


Using molecular markers, number and position of valuable alleles for somequantitative loci can be identified. An ideal genetic marker must be: polymorphic,multiallelic, codominant and environmentally not sensitive. These conditions areaccomplished by RFLP markers. Pit 1 and k-casein gene have been shown to beinvolved in milk yield/quality (protein, fat content) in cattle. The alleles favourablefor selection are B for k-casein and A for Pit1, both being associated with higherprotein content and superior milk yield for Pit-1.The present study was carried outto establish the genotype and allele frequencies for k-casein and Pit-1 genes usingPCR-RFLP/HinfI technique in 76 Romanian Simmental cattle.
