[Methods]By studying molecular markers of fat content in sheep muscle,the CAPN gene was used to find polymorphic sites related to fat content in sheep muscle,and the correlation between two polymorphic sites C724 A and A601G on CAPN1 and CAPN2 and fat content in sheep muscle was analyzed. [Results] The two polymorphic sites,C724 A on CAPN1 and A601G on CAPN2 were significantly related to intramuscular fat in mutton. [Conclusions] These two molecular markers can be used as a molecular marker reference when breeding high-quality meat or hair and meat using German Merino sheep breeds.展开更多
