摘要: Myostatin, which is a highly con servative gene among breeds, is a negative regulator of muscle The 3' coding reg ion of wild boar and crossbred pig myostatin was cloned by RT-PCR and sequenced Compared with that of GenBank, the homology of the nucleotide sequence between wild boar and crossbred pig is identical in this region indicating that domestic pigs were evolved from wild boar and there was not changed in this region durin g the evolution processes
