Distribution of ABO blood group in Tibetan population and their genetic relationship / 中南大学学报(医学版)

ABSTRACT

Objective To explore the distribution of ABO blood group in Tibetans population and their genetic relationship. Methods Data of ABO blood group of 28 Titetan populations were collected from China and India. The gene frequencies were processed by Phylip3. 68 and MEGA4. 1 genetic analysis software pack, and the Nei's genetic distance was imported and the genetic relationship was analyzed. Results The distribution of ABO blood group among Gansu, Qianghai, Sichuan, Yunnan, Tibet, and India was 0 ＞ A ＞ B ＞ AB. The nation index and genetic distance were 0. 63 ～ 0.98 and 0 ～0. 0072, respectively. Conclusion There is probable historical relationship among the ancestors of these Tibetan populations, but the differentiation incident of Tibetan population living in different area in history was different, so that their distribution of gene frequencies is diversified.
