THE STUDY OF POPULATION GENETIC RELATION AMONG TEN ETHNIC GROUPS IN NORTHWEST CH INA

Objective To investigate the genetic relation am on g ten ethnic groups in northwest China. Methods Allele frequ encies of six STR(short tandem repeat ) loci in D13S1358, VWA, FGA, D5S818, D13S 317, and D7S820 were collected from Lasa Tibetan, Changdu Tibetan, Xi'an Han, G ansu Dongxiang, Gansu Yugu, Xinjiang Uygur, Ozbak, Kirgiz, Sibe, Ningxia Hui by the results of State Key laboratory, Forensic Science Department, school of medi cal, Xi'an Jiaotong University and internet biological information data bank, a nd compared with that of the Mongolian, Zhuang in China, and White and Negro in USA. The polymorphism index (H, DP, PPE, PIC) and genetic distance, then the phy logenetic tree of all population were reported. Results The res ulting tree topology exhibited strong geographic and racial partitioning consist ent with that obtained with HLA and classical genetic polymorphisms. Conclusion The results suggest that forensic STR loci may be particular ly powerful tools and provide the necessary fine resolution for the reconstructi on of recent human evolutionary history.

Indigenous Knowledge on Soil Classification of Ethnic Groups in Luang Prabang Province of the Lao PDR

The objectives of this study were to demonstrate ethno-scientific elicitation techniques in retrieving indigenous knowledge at village-level, and to document the indigenous soil classification systems of different ethnic groups in Luang Prabang province in the Lao PDR. The study area comprised three villages – Nambo, Huaymaha and Thapo, in the Phonxay district of Luang Prabang province. Three ethnic groups were covered by the study – Hmong, Khmu and Lao Loum. All three ethnic groups used soil color as main criteria for soil classification. However, even within the same ethnic group, sometimes different villages have differences in the way they classify soils; this was apparent for the Hmong ethnic group in the villages of Huaymaha and Nambo. A significant difference of the Lao Loum ethnic group from the other two, was the emphasis used in classifying soil types according to their water holding capabilities. In contrast, the Khmu and Hmong classified many soil types in relation to their rock content (‘with rock’ or ‘pure rock’ sometimesbeing used). The results of the study suggest that the ethnic groups classify the soils in relation to their potential for different types of agricultural production.

Common Development of All Ethnic Groups

China’s ethnic minorities not only enjoy the equal rights with the majority Hans as endowed by the Constitution and other laws, but also enjoy the right to regional autonomy in areas where minorities live in compact communities. In February 2001, the NPC Standing Committee revised the law on ethnic regional autonomy for minorities, adding new provisions on increasing investment in the areas of ethnic minorities to accelerate local development.

Upholding Equality and Unity Among Ethnic Groups, and Freedom of Religious Belief

Since the founding of the People＇s Republic of China, the Chinese government, to ensure equality and unity among ethnic groups and achieve their common development, has formulated a series of ethnic and religious policies on the basis of the actual situations of the various ethnic groups and religions, and these policies have been continuously enriched and improved in practice.

They can also be found in Heilongjiang and Liaoning provinces and the Inner Mongolia Autonomous Region, They have their own spoken and written language, Korean. which is also the official language of South and North Korea. The ancestors of the Korean ethnic group - mostly peasants fleeing their oppressive feudal landlords - migrated from the Korean Peninsula around the late 17th century. When they settled down in China they gradually formed unique customs, Today.

Mongolian AN ethnic group known for ＂growing up on horsebacks,＂ the Mongolians live mostly in the In- ner Mongolia Autonomous Region in the northern part of China, which includes vast tracts of excel- lent natural pastureland with numerous herds of cattle, sheep, horses and camels. The rest are also distributed in Liaoning Jilin. Heilongjiang. Qinghai and Gansu provinces. Living on grasslands and relying on raising stock as their economic mainstay, the Mongolians have kept their nomadic living style for hundreds of years. Mongolian herdsmen used to live in yurts,which were usually seven to eight feet high and 10 feet in diameter, with an opening in the top of the umbrella-shaped roof. The structure can offer ideal ventilation and good protection against wind and cold. After the mid-20th century, as more and more herdsmen ended their nomadic life and settled down, they began to build yurt-like houses made of mud and wood.

DongTHE Dong people live mainly in Guizhou and Hunan provinces though they can also be found in the Guangxi Zhuang Autonomous Region, as well as Jiangsu, Guangdong and Zhejiang provinces. In addition to agriculture, they make their living by growing timber trees, which are then logged and sold. Trees are so important in their lives that they have a unique custom of planting 18 fir trees when a child is born. When the child reaches the age of 18 and gets married, the matured fir trees are felled and used to build houses for the bride and groom

Endogamous marriage and the prevalence of hemoglobin E in ethnic groups of northern Thailand

Objective:To investigate the impact of the endogamous marriage culture on the prevalence of the hemoglobin E(HbE) recessive variant.Methods:The prevalence of the hemoglobin E(HbE)recessive variant was determined by dot-blot hybridization in 4 endogamous villages(1 Mlabri and 3 Htin ethnic groups) in comparison with 9 other nearby non-endogamous populations.Results:Although the overall HbE prevalence in the population studied(8.44%,33/391)was not significantly different from that of the general southeast Asian population,a high prevalence and individuals with homozygous HbE were observed in two villages,the Mlabri from Wiang Sa district and the Htin from Thung Chang district of Nan province(26.3%and26.9%,respectively).The low HbE allelic frequency noticed in some endogamous populations suggests that not only endogamy but also other evolutionary forces,such as founder effect and HbE/β-thalassemia negative selection may have an effect on the distribution of the HbE trait.Conclusion:Our study strongly documents that cultural impact has to be considered in the extensive prevalence studies for genetic disorders in the ethnic groups of northern Thailand.

The Historical Role of the Policy of National Common Language on the Development of Ethnic Groups

In the work concerning ethnic groups in the People's Republic of China,the Communist Party of China(CPC)and the state adopted the policy of promoting national common language in line with the needs of ethnic development,while safeguarding the rights of various ethnic groups in using their languages.This paper reviews the role of the policy of national common language in facilitating the development of ethnic areas in different historical periods of China.It is believed that this practical and gradual policy of language conforms to the needs of social,economic and cultural development in different periods in China,which greatly improves the comprehensive abilities of the people of all ethnic groups and turns the Chinese nation into a community of shared future with higher acceptance and stronger cohesion.
