The Asian crowd studies and obtains the newest achievement in hereditary variety
It is reported ' Reporter Hu DeRong) Recently, the newest achievement studied as Asian crowd's hereditary variety, is " suffused with the inferior SNP plan " First period publish achievement at being here Science. Chinese Academy of Sciences - Ma Pu society calculates the biological chief of partner's research institute, the intersection of money and the intersection of strength and Professor and the intersection of Chinese Academy of Sciences and the intersection of Shanghai and the intersection of life and academy of sciences, Vice President of Fudan University, calculate biology the intersection of book and Assistant Researcher Hua Xu the common the intersection of communication and author of research results, responsible for data analysis and thesis writing. It is introduced, are " suffused with the inferior SNP plan " Started in 2005 formally, is participated in together by the scientific research personnel of 11 countries and regions such as China, India, Japan, South Korea,etc., aim at utilizing genetic technology, announce Asians in terms of science of heredity, it is specially migration routes of the ancestor of native in East Asia. In the individual event type gene is measured, the most noticeable one is to the single alkali Quito attitude (SNP) Determination,it is only about DNA it is particular the at position one base the analyses of arrays single. Through the research of nearly 4 years, this project has collected more than 70 more than 1700 samples that Asia represent the crowd which covers East Asia, South Asia and Southeast Asian every area together, and carried on the gene dividing type of the whole genome. This discovers, hereditary structure and the crowd's language structure of the Asian crowd have very good corresponding relation, Altai, Chinese hide, Miao have a corresponding one by Yao, the intersection of Dong and the intersection of Dai, South Asia, south island,etc. and family of languages but hereditary composition of recognition, its relevance is even higher than the relation of hereditary structure and the crowd's geographical distribution, prove the modern crowd's flowability is very big, but the cohesiveness of the culture language is still very strong. On the other hand, discover most crowds in a normal sense all include a plurality of hereditary components, prove the genetic exchange between the Asian crowds is quite frequent. Distribute and the decreasing mode of gradient from south to the north of hereditary variety in the typical north and south of the crowd in East Asia, have announced in the South origin of the intersection of East Asia and crowd and prehistoric and moved to history northwards. The research has suggested, the modern Asian crowd's basic heredity structural characteristic and geographical distribution mode are mainly results that the crowd moves before being early. This research has announced the meticulous hereditary structure of the Asian crowd from the whole genome level, the system has expounded the relation between Asian crowd's hereditary structure and geographical distribution and language structure.
