The genetic divergence of R1a (M420) is estimated to have occurred 25,000 [2] years ago, which is the time of the last glacial maximum.A 2014 study by Peter A. Underhill et al., using 16,244 individuals from over 126 populations from across Eurasia, concluded that there was "a compelling case for the Middle East, possibly near present-day Iran, as the geographic origin of hg R1a".

Haplogroup R1a is one of the major classifications (called clades) of Y-chromosome types found in human male lines.It is widespread all across Eurasia.Many sample studies therefore carry information on the incidence of R1a and/or its subclassifications, in particular the dominant branching line represented by the haplogroups R1a1 and R1a1a.
The proposed candidates include haplogroup C3, haplogroup Q, haplogroup R1b and haplogroup C2. [ 50 ] Y chromosome haplogroup C2c1a1a1-M407 is carried by Mongol descendants of the Northern Yuan ruler from 1474–1517, Dayan Khan , who is a male line descendant of Genghis Khan which was found out after geneticists in Mongolia conducted tests on ...
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.

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.
The R1a-Z93 paternal genetic in Romani people was also discovered. [10] Indian-Brahmin origin of paternal haplogroup R1a1*. [11] The Haplogroup R2 is mainly restricted to various populations of South Asia, in addition to some populations of South Central Asia, Middle East, Asia Minor and the Caucasus where it is observed in low frequencies.

According to the research of Peter L. Nagy, Judit Olasz and others, the lifetime of a common ancestor between the Bashkir R1a-SUR51 and the Arpad dynasty falls on the beginning of our era. [13] Another researcher Bulat A. Muratov displays the time of the divergence of the Bashkirs R1a-SUR51 from the Arpad dynasty to the 7th century AD. [14]
Haplogroup R. R0 or pre-HV. R0a or (preHV)1: Occurs commonly in the Arabian peninsula, with its highest frequency observed among the Soqotri. [14] Moderate frequencies found in North Africa, the Horn of Africa, and Central Asia. HV: It is a west Eurasian haplogroup mainly found throughout the Middle East, including Iran. [15]
