A total of 110 males of Portuguese descent were analyzed for 17 Y-chromosome bi-allelic markers and seven Y-chromosome short tandem repeats (Y-STR) loci.
We prepared a next generation sequencing (NGS)-based target sequencing panel of 85 Y-SNPs to determine Y-haplogroup of Asian populations.
Although Y-STR typing seems more widely used in forensic casework and convenient to predict haplogroup with online tools, our finding suggested that the occurrence of errors in Y-chromosome haplogroup prediction should be cautious.
This review considers genome-scale evidence on ancient Y chromosome diversity that has recently started to accumulate in geographic areas favourable to DNA preservation.
Studies of Y-chromosome diversity in other great apes are relatively undeveloped compared to those in humans, but have nevertheless provided insights into speciation, dispersal, and mating patterns.
Studies of the Y chromosome over the past few decades have opened a window into the history of our species, through the reconstruction and exploitation of a patrilineal (Y-genealogical) tree based on several hundred single-nucleotide variants (SNVs). A new study validates, refines and extends this tree by incorporating >65,000 Y-linked variants identified in 1,244 men representing worldwide diversity.
Five subethnic groups of Tobol–Irtysh Siberian Tatars (N = 388 samples) have been analyzed for 50 informative Y-chromosomal SNPs.
Results have been obtained from 16 males from the EN cemeteries Lokomotiv and Shamanka II representing haplogroups K, R1a1 and C3, and 20 males from the LN-EBA Ust’-Ida and Kurma XI cemeteries representing haplogroups Q, K and unidentified SNP (L914).
