Abstract

This study was performed to investigate two polymorphic sites from GENE/fa?page=1&sort=1&ftyp=all&fgrp=all&fyrs=all" target="_blank"> CYP19 GENE (PvuII and MspI) and one polymorphic site from ERα GENE (SnaBI) in four CATTLE BREEDS including Mazandarani, Taleshi, Sistani and Simmental. In overall 278 samples for CYP19 and 206 samples for ERα marker sites were genotyped using polymerase chain reactionsingle-strand conformation polymorphism (PCR-RFLP) procedure. For CYP19/PvuII, the frequency of A allele ranged from 0.89 in Mazandarani to 0.98 in Taleshi. For CYP19/MspI, Taleshi was the only monomorphic breed with just AA genotype. Other breeds were polymorphic with A allele frequency ranging from 0.93 (Simmental) to 0.98 (Sistani). No BB individuals were observed in the studied sample. Considering two loci in combination with each other, only 5 out of 8 theoretically possible combined genotypes were observed in the genotyped samples. For ERa/SnaBI, all populations showed polymorphism. The highest and lowest frequencies of A allele were observed in Sistani (0.55) and Simmental (0.96), respectively. Based on Nei’s method, the most GENEtic distance was observed between Sistani and Simmental and the least GENEtic distance was observed between Mazandarani and Taleshi breeds. The results of the present study showed significant differences in genotypic and allelic frequencies among four investigated breeds. These findings may be used in further researches, such as association studies for performance traits in cattle breeding.
