Abstract: This study is to reveal the polymorphism of DYF155S1 locus, Y-specific minisatellite, among 136 cases unrelated male in Bai population of Yunnan Province.The analytical methods include Amp-FLP (Amplified fragment length polymorphism) and MVR-PCR (minisatellite variant repeat by PCR) with type 1-specific primer at 5′end and type 4-specific primer at 3′end. It is found that DYF155S1 locus possesses a high polymorphism and its gene diversity (h) reaches 0. 9996. These results indicated that Amp-FLP in combination with MVR-PCR may reveal fully the polymorphism of DYF155S1 locus and provide a useful tools and more data for the field of human genetics, anthropology and forensic medicine.
