The allele T dominated in the imported lean-type pig breeds such as Yorkshire, Landrace and Duroc. No allele A was detected in Junmu and Sanjiang white pig, and the frequencies of three genotypes were about equal in Min pig. The result using X2 analysis showed that the distribution of three genotypes was related to pig breeds.展开更多
