Genetic structure among 38 populations from the United States based on 11 U.S. core Y chromosome STRs

A DNA database consisting of the 11 Y chromosome short-tandem-repeat (Y-STR) recommended by the Scientific Working Group on DNA Analysis Methods is constructed for 2517 individuals from 38 populations in the United States. The population samples derive from five ethnic groups currently living in 10 states. A multidimensional scaling (MDS) plot places the populations into four discrete clusters (African Americans (AA), European Americans (EA), Hispanic Americans (HA), and Asian Americans (SA)) and one dispersed cluster of Native Americans. An analysis of molecular variance (AMOVA) indicates that a large proportion of the total genetic variance is partitioned among ethnic groups (24.8%), whereas only a small amount (1.5%) is found among-populations within ethnic groups. Separate AMOVA analyses within each ethnic group show that only the NA sample contains statistically significant among-population variation. Pair wise population differentiation tests do uncover heterogeneity among EA and among HA populations; however, this is due to only a single sample within each group. The analyses support the creation of AA, EA, HA, and Asian American databases in which samples from different geographic regions within the United States are pooled. We recommend that separate databases be constructed for different NA groups.     

Allelic variation at ACTBP2 microsatellite for two Indian tribal groups

POPULATION: Two tribal populations, Bison Horn Maria ( N =49) and Muria ( N =52) from Bastar district in Central India.     

Population data at two short tandem repeat loci D2S1338 and D19S433 in the sample of multinational Bosnia and Herzegovina residents

POPULATION: We have analyzed the distribution of allele frequencies at two short tandem repeats loci (D2S1338 and D19S433) in a multinational sample of Bosnia and Herzegovina (B&H) residents. A total of 110 unrelated male and female individuals (Caucasians) from different regions of B&H were sampled for the analysis. We ensured that the sample reflected approximate proportional participation of the three main ethnic groups in the population of B&H (Bosniacs-Muslim [45%], Serbs [34%], Croats [21%]).     

Genetic analysis of 15 STR loci of Chinese Ewenki ethnic population

POPULATION: Almost all the Ewenki are found in HulunBuir Ewenki Autonomous Banner, Inner Mongolia province of China. Some Ewenki are nomads; others are farmers or farmer-hunters. A small number of them are hunters. Its national characters and languages belong to the Altai phylum.     

Genetic analysis for Y chromosome short tandem repeat haplotypes of Chinese Han population residing in the Ningxia province of China

POPULATION: One hundred and one unrelated, autochthonous healthy males of the Chinese Han population living in Yongning county of the Ningxia Hui Autonomous Region of China.     

Genetic analysis of six STR polymorphisms in a southern Chinese population

POPULATION: A total of 105 unrelated and healthy individuals from the Han ethnic group of Nanning city in south China.     

中国鄂温克族DXS7423，DXS7424，DXS7132，DXS7133，DXS6804位点多态性的研究

目的以无关个体为研究对象,研究鄂温克族人群X染色体5个STR位点的遗传多态性,建立群体遗传数据库。方法用聚合酶链反应(PCR)、变性聚丙烯凝胶电泳和银染的方法,检测98名中国鄂温克族DXS7423,DXS7424,DXS7132,DXS7133,DXS6804位点的重复序列长度的变化。结果5个STR位点在鄂温克族群体均具有遗传多态性,χ2检验表明多态性分布符合Hardy-Weinberg平衡定律。结论中国鄂温克族X染色体5个STR基因座群体遗传数据资料,可用于法庭科学个体识别、亲子鉴定及其他人类学研究。
