Haplogroup R1a (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.

History and description of Haplogroup R1a (Y-chromosomal DNA) and its subclades. Haplogroup R1a is the dominant paternal lineage in Northeast Europe and southern Central Asia. It was diffused around Eurasia by the Indo-Aryans and Balto-Slavic people.

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.

Haplogroup R1, or R-M173, is a Y-chromosome DNA haplogroup. A primary subclade of Haplogroup R (R-M207), it is defined by the SNP M173. The other primary subclade of Haplogroup R is Haplogroup R2 (R-M479).

Mar 26, 2014 · Whole Y-chromosome sequence analysis of eight R1a and five R1b individuals suggests a divergence time of ∼ 25 000 (95% CI: 21 300–29 000) years ago and a coalescence time within R1a-M417 of ∼...

With a 95% probability, the most recent common ancestor of all members of haplogroup 3889 2652 BCE. She is the ancestor of at least 5 descendant lineages known as R1a1 and 4 yet unnamed lineages. Descendant lineages are identified as …

Family Tree DNA's haplogroup description of R1a: R1a - The R1a lineage is believed to have originated in the Eurasian Steppes north of the Black & Caspian Seas. This lineage is thought to descend from a population of the Kurgan culture, known for …

It discusses genetic markers and subclades of R1a, the interactions between R1a populations and other Y-DNA haplogroups, and their subsequent diffusion into Central and Northern Europe, providing insights into the genetic landscape of these regions during the Bronze Age.

This study focuses on DNA lineages, or branches, of hap-logroup R1a in Europe, from the Atlantic to the Ural Mountains, and on the history of their appearance and migrations across and from Europe in the last ~9000 years (Appendix 1). The methodology of the study, based largely on considerations of

Aug 9, 2023 · The Y-DNA haplogroup R1a is a thread woven through the tapestry of human history. It is one of the most widespread paternal lineages, particularly in Eurasia. In this article, we will unravel the intricate patterns of R1a subclades and explore their connections with ancient peoples and civilizations, based on recent scientific studies.
