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.

R1a被认为是北部和东部的原始印欧语族群中的主导单倍群，并分化为印度伊朗、色雷斯、波罗的海和斯拉夫各分支。 原始印欧人起源于公元前3,300-2,500年的颜那亚文化，他们的剧烈扩张可能得益于更早的采用青铜武器以及在欧亚草原上对马的驯化（约公元前4,000-3,500年）。 南部草原文化被认为主要是R1b (M269和M73)主导，而北部森林草原文化则是R1a主导。 森林草原人群的初次扩张发生在 绳纹器文化 时期（参考下面的日耳曼分支），Catacomb文化时期 (公元 …

单倍群r1a的亞歐大陸分佈情況. 单倍群r-m420 ，isogg名稱為单倍群r1a，是一種人类y染色体dna单倍型类群，與單倍群r1b共同源與單倍群r1，歐亞大陸主要分佈，北起斯堪的纳维亚，南至中欧，東至中亚、西伯利亚南部和南亚。 [3] 有一项基因研究表明r1a起源于25,000 [1] 年前。

Find out which of the R1a branches and 28 countries that you belong to with the most comprehensive mtDNA test! Every new mtFull Sequence test result helps improve the tree structure and age estimates. A popular genealogy strategy is to expand your part of the tree by encouraging distant relatives to test.

Here, we report the variation of 486 Y-chromosomes within the Ashkenazi and non-Ashkenazi Levite R1a clade, other Ashkenazi Jewish paternal lineages, as well as non-Levite Jewish and non-Jewish R1a samples.

Y-DNA haplogroup R1a. This haplogroup originated around 25000 BC to 22000 BC in the populations of Eastern European Hunter-Gatherers connected genetically to Ancient North Eurasians. The earliest subclades R1a-Z645 and R1a …

R1a-M420 is one of the most widely spread Y-chromosome haplogroups; however, its substructure within Europe and Asia has remained poorly characterized. Using a panel of 16 244 male subjects from 126 populations sampled across Eurasia, we identified 2923 R1a-M420 Y-chromosomes and analyzed them to a highly granular phylogeographic resolution.
