Abstract

The Forest and Tundra Nenets in different areas of the Yamalo-Nenets Autonomous Okrug were studied using Y-chromosome markers. The results of analyzing the genetic structure of Nenets clans using 44 STR markers of the Y chromosome are presented, taking into account their presence in subethnoses (Tundra and Forest Nenets), as well as to the Kharyuchi ("true Nenets") and Vanuito ("foreigners") phratries. The number of the Nenets (N = 606) includes the Tundra (N = 536) and Forest (N = 70) Nenets. Sublineage N1a2b1b1a~-B170 is specific for the clans in the Kharyuchi phratry, and sublineage N1a2b1b1b-B172, for the clans in the Vanuito phratry. Most Forest Nenets clans have haplogroup N1a2b1-B478. All males of the Pyak clan, which is prevalent in the Forest Nenets, have a specific haplogroup, N1a1a1a1a2a1c1~. The results of the study suggest that the Nenets clan associations typically have a common ancestor in the male line and are characterized by a recent founder effect. Each Nenets clan has its own specific cluster of haplotypes, equidistant from each other. The structure of Y-chromosome haplotypes and haplogroups in the Nenets gene pool includes the Nenets heritage from the Khanty and Enets. Many samples from these sample sets were shown to have rare haplotypes that were absent from the baseline data and to differ significantly from the other haplotypes found in the populations. They belong to various rare branches of the Y-chromosome haplogroups found only in these sample sets. Some samples form haplotype variants that have not been described previously and allow us to characterize the phylogeny of these lineages in more detail. The Forest and Tundra Nenets differ greatly in the composition of haplogroups, which is fully consistent with ethnological and linguistic data on the origin of these populations. The predominant haplogroups are N1a1a1a1a2a1c1~-Y13850, Y13852, Y28540 CTS9108 (xY24219, Y24375) and N1a2b1-B478, Z35080, Z35081, Z35082, Z35083, Z35084 (xB169) in the Forest Nenets, and N1a2b1b1a~-B170 (xZ35104), N1a1a1a1a2a1c~-Y13850, Y13852, Y13138, PH3340 (xY24219, Y24365) and N1a2b1b1b-B172, Z35108 in the Tundra Nenets.

森林涅涅茨人和苔原涅涅茨人:y染色体单倍群的差异。
利用y染色体标记对亚马尔-涅涅茨自治区不同地区的森林涅涅茨人和冻土带涅涅茨人进行了研究。利用Y染色体的44个STR标记分析涅涅茨部族的遗传结构的结果被提出,考虑到它们存在于subbeth鼻(苔原和森林涅涅茨人),以及Kharyuchi(“真正的涅涅茨人”)和vanuto(“外国人”)部落。涅涅茨人(N = 606)包括苔原(N = 536)和森林(N = 70)涅涅茨人。N1a2b1b1a~-B170亚系为Kharyuchi氏族所特有,N1a2b1b1b-B172亚系为vanuto氏族所特有。大多数涅涅茨森林族都有单倍群N1a2b1-B478。在森林涅涅茨人中普遍存在的Pyak族的所有雄性都有一个特定的单倍群n1a1a1a2a1c1 ~。研究结果表明,涅涅茨氏族协会通常有一个共同的男性祖先,并以最近的创始人效应为特征。每个涅涅茨部族都有自己特定的单倍型群,彼此之间距离相等。涅涅茨人基因库中的y染色体单倍型和单倍群结构包括来自汉特人和埃涅茨人的涅涅茨人遗传。来自这些样本集的许多样本显示具有基线数据中不存在的罕见单倍型,并且与种群中发现的其他单倍型显著不同。他们属于只在这些样本组中发现的y染色体单倍群的各种罕见分支。一些样本形成了单倍型变异,以前没有描述过,这使我们能够更详细地描述这些谱系的系统发育。森林涅涅茨人和苔原涅涅茨人在单倍群的组成上有很大的不同,这与关于这些种群起源的民族学和语言学数据完全一致。主要单倍群为森林涅涅茨地区的n1a1a1a2a1c1 ~-Y13850、Y13852、Y28540、CTS9108 (xY24219、Y24375)和N1a2b1-B478、Z35080、Z35081、Z35082、Z35083、Z35084 (xB169),以及苔原涅涅茨地区的N1a2b1b1a~-B170 (xZ35104)、n1a1a1a2a1c ~-Y13850、Y13852、Y13138、PH3340 (xY24219、Y24365)和N1a2b1b1b-B172、Z35108。
