The frequency of T1a and T2 in Yamna samples were each 14.5%, a percentage higher than in any country today and only found in similarly high frequencies among the Udmurts of the Volga-Ural region. [7] Haplogroup T has also been found among Iberomaurusian specimens dating from the Epipaleolithic at the Afalou prehistoric site in Algeria.
(Data from studies conducted before 2004 may be inaccurate or a broad estimate, due to obsolete haplogroup naming systems – e.g. the former Haplogroup 2 included members of the relatively unrelated haplogroups known later as Haplogroup G and macrohaplogroup IJ [which comprises haplogroups I and J].)

Y-DNA haplogroup migration in East Asia. The tables below provide statistics on the human Y-chromosome DNA haplogroups most commonly found among ethnolinguistic groups and populations from East and South-East Asia. ST means Sino-Tibetan languages.
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.
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 ...
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.
