To reconstruct the phylogenetic structure of Y-chromosome haplogroup (hg) C in populations of northern Eurasia, we have analyzed the diversity of microsatellite (STR) loci in a total sample of 413 males from 18 ethnic groups of Siberia, Eastern Asia and Eastern Europe. Analysis of SNP markers revealed that all Y-chromosomes studied belong to hg C3 and its subhaplogroups C3c and C3d, although some populations (such as Mongols and Koryaks) demonstrate a relatively high input (more than 30%) of yet unidentified C3* haplotypes. Median joining network analysis of STR haplotypes demonstrates that Y-chromosome gene pools of populations studied are characterized by the presence of DNA clusters originating from a limited number of frequent founder haplotypes. These are subhaplogroup C3d characteristic for Mongolic-speaking populations, "star cluster" in C3* paragroup, and a set of DYS19 duplicated C3c Y-chromosomes. All these DNA clusters show relatively recent coalescent times (less than 3000 years), so it is probable that founder effects, including social selection resulting in high male fertility associated with a limited number of paternal lineages, may explain the observed distribution of hg C3 lineages.

The origin of domestic sheep (Ovis aries) can be traced back to the Asian mouflon (Ovis gmelini), in the Near East around 10 000 years ago. Genetic divergence within mouflon populations can occur due to factors such as geographical isolation, social structures, and environmental pressures, leading to different affinities with domestic sheep. However, few studies have reported the extent to which mouflon sheep contribute to domestic sheep in different regions.

Y-chromosomal short tandem repeats (Y-STRs) at rapidly mutating (RM) loci have been suggested as tools for differentiating paternally related males. RMplex is a recently developed system that incorporates 26 RM loci and four fast-mutating (FM) loci, targeting 44 male-specific loci. Here, we evaluated the RMplex by estimating Y-STR mutation rates and the overall differentiation rates for 542 Korean father-son pairs, as well as the genetic population values for 409 unrelated males.

Genetic markers of the Y chromosome are powerful tools for investigating paternal ancestry and are widely used in population and forensic genetics. However, in order to obtain statistics with a higher degree of certainty using these markers, it is necessary to obtain haplotypic frequencies from a representative database, as well as knowing the diversity and structure of the population. The aim of this study was to investigate the genetic diversity of a sample of 1114 unrelated men from three states in the Northeast of Brazil: Paraíba, Pernambuco and Ceará, through the analysis of 23 Y-STRs and to contribute to the expansion of the Brazilian database on these markers.

Eastern Finnic populations, including Karelians, Veps, Votes, Ingrians, and Ingrian Finns, are a significant component of the history of Finnic populations, which have developed over ~3 kya. Yet, these groups remain understudied from a genetic point of view. In this work, we explore the gene pools of Karelians (Northern, Tver, Ludic, and Livvi), Veps, Ingrians, Votes, and Ingrian Finns using Y-chromosome markers (N = 357) and genome-wide autosomes (N = 67) and in comparison with selected Russians populations of the area (N = 763).

This study investigates the Y-chromosome genetic diversity of the Turkmen population in Turkmenistan, analyzing 23 Y-STR loci for the first time in a sample of 100 individuals. Combined with comparative data from Turkmen populations in Afghanistan, Iran, Iraq, Russia, and Uzbekistan, this analysis offers insights into the genetic structure and relationships among Turkmen populations across regions across Central Asia and the Near East. High haplotype diversity in the Turkmen of Turkmenistan is shaped by founder effects (lineage expansions) from distinct haplogroups, with haplogroups Q and R1a predominating.
