In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by specific mutations in the non-recombining portions of DNA on the male-specific Y chromosome (Y-DNA). Individuals within a haplogroup share similar numbers of short tandem repeats (STRs) and single-nucleotide polymorphisms (SNPs). [ 2 ]
The following articles are lists of human Y-chromosome DNA haplogroups found in populations around the world. Y-DNA haplogroups by ethnic group;
Y1a appears to be a relatively young haplogroup, with an age of 6,000 (95% CI 3,300 <-> 8,800) years estimated from 13 complete genomes (Ulchi x 6, Nivkh x 3, Koryak x 2, Even x 1, Mongolian x 1); however, this estimate may be relevant only for the TMRCA of Y1a2 and most Y1a* and Y1a-T16189C haplotypes, as it is not certain that any of the Y1a ...
In human population genetics, Y-Chromosome haplogroups define the major lineages of direct paternal (male) lines back to a shared common ancestor in Africa. Men in the same haplogroup share a set of differences, or markers, on their Y-Chromosome, which distinguish them from men in other haplogroups.
A haplotype is a group of alleles in an organism that are inherited together from a single parent, [1] [2] and a haplogroup (haploid from the Greek: ἁπλοῦς, haploûs, "onefold, simple" and English: group) is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation. [3]

The table below shows the human Y-chromosome DNA haplogroups, based on relevant studies, for various ethnic [dubious – discuss] and other notable groups from Europe.The samples are taken from individuals identified with the ethnic and linguistic designations shown in the first two columns; the third column gives the sample size studied; and the other columns give the percentage for each ...
Haplogroup H (Y-DNA), also known as H-L901/M2939, is a Y-chromosome haplogroup. The primary branch H1 (H-M69) and its subclades is one of the most predominant haplogroups amongst populations in South Asia , particularly its descendant H1a1 (M52).
