This article reports studies on polymorphisms of the ATP-binding cassette superfamily G member 2 transporter (ABCG2) gene in 68 Chinese buffalo and 80 yak by DNA sequencing. We found four mutations: A deletion, G insertion, single nucleotide polymorphisms (SNPs) G/A and C/A. A deletion existed in the buffalo and yak breeds. G insertion, (G/A) and (C/A) SNPs existed only in the buffalo breed. Results showed the Chinese buffalo and yak breeds had four mutations. Especially, the buffalo breed had four mutations at least, and the these probably affected the milk yields, milk fat, protein and dry matter percent. So the ABCG2 gene could be studied as a candidate gene effecting milk traits.
