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 ]

Map showing frequency of R1a haplogroup in Europe. Haplogroup R1a, or haplogroup R-M420, is a human Y-chromosome DNA haplogroup which is distributed in a large region in Eurasia, extending from Scandinavia and Central Europe to Central Asia, southern Siberia and South Asia. [3] [2]
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 .
Haplogroup Q or Q-M242 is a Y-chromosome DNA haplogroup. It has one primary subclade, Haplogroup Q1 (L232/S432), which includes numerous subclades that have been sampled and identified in males among modern populations. Q-M242 is the predominant Y-DNA haplogroup among Native Americans and several peoples of Central Asia and Northern Siberia.
Map of Y-Chromosome Haplogroups - Dominant haplogroups in pre-colonial populations with proposed migration routes. A "Central Siberian" origin has been postulated for the paternal lineage of the source populations of the original migration into the Americas. [48] Membership in haplogroups Q and C3b implies Indigenous American patrilineal ...
World map of early migrations of modern human beings based on the Y-chromosome DNA.. South Asia, located on the crossroads of Western Eurasia and Eastern Eurasia, accounts for about 39.49% of Asia's population, [1] and over 24% of the world's population. [2]
The second wave of migration took a more northerly course, splitting somewhere in the area around what is now called Syria to sweep to interior Asia, where it split several more times in Central Asia, north of Afghanistan. The lineages that flowed into Central Asia carry M9 (Haplogroup K (Y-DNA)). Other markers were added after the migration ...
