摘要

Y染色体特异性短串联重复标记存在于Y染色体的非重组部分,是父系遗传的。这些特性使Y-STRs成为调查性侵犯和其他暴力犯罪、亲子关系案件、家谱测试和进化研究的有用工具。土著居民居住在秘鲁的海岸、山区和丛林中;然而,梅斯蒂索人是秘鲁人口最多的群体。结果在290份样本中,观察到283种不同的单倍型。各Y-STR标记的基因多样性范围为0.4271 ~ 0.8597。总样本的单倍型多样性为0.9964。结论通过多维尺度和系统发育树分析,确定了秘鲁混血儿群体与其他秘鲁群体(除Jivaro、Awajun和Shipibo-Conibo群体)和玻利维亚混血儿群体之间的遗传亲缘关系

Analysis of 27 Y-chromosomal STR loci of the Mestizo Peruvian population
Abstract Background Y-chromosome-specific short tandem repeat markers reside on the non-recombinant portion of the Y chromosome and are paternally inherited. These properties make Y-STRs a useful tool in investigations of sexual assault and other violent crimes, paternity cases, genealogical testing, and evolutionary studies. Native populations reside in the Peruvian coast, mountains, and jungle; however, the Mestizos are the largest population group in Peru. Results Of the 290 samples, 283 distinct haplotypes were observed. Gene diversities for each Y-STR marker ranged from 0.4271 to 0.8597. The haplotype diversity for the total sample was 0.9964. Conclusions Genetic affinity was identified between the Peruvian Mestizo population and other Peruvian populations (except Jivaro, Awajun, and Shipibo-Conibo populations) and Bolivian Mestizo populations using multidimensional scaling and phylogenetic tree analysis
