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, Swati tribe and several peoples of Central Asia and ...

There are 4,690 DNA tested descendants, and they specified that their earliest known origins are from Mexico, United States (Native American), Colombia, and 111 other countries. This information is self-reported by FamilyTreeDNA participants.

2019年1月24日 · To assess the timing, places of origin and extent of admixture between these components, we performed an analysis of the Y-chromosome haplogroup Q, which is the only Pan-American haplogroup and accounts for virtually all Native American Y chromosomes in Mesoamerica and South America.

单倍群q属于人类y染色体dna单倍型类群之一，由基因标记m242定义，在全球均有低频分布，美洲土著有高频分布。

NEW SNP Discovery: During Walk Through the Y (WTY) testing, the project tested 23 Q-M242 men with an average SNP marker discovery rate of 3.5 per sample. In November 2013, Family Tree DNA introduced their new BIG Y product that has 30 times the Y-DNA coverage of Walk Through the Y. To date, the project has had around 120 orders for BIG Y.

2021年8月15日 · Y染色体单倍群Q1a1a-M120（又简称Q-M120 或 M120）是汉族的父系祖源之一，这是一个事实，没有人能够否认，该单倍群在南方汉族和北方汉族中有着广泛的分布。 吉林大学赵永斌等人的研究表明，Q-M120单倍群参与构成中国境内 华夏先民 父系基础，年代可以追溯到公元前1000年左右。 但是，关于Q-M120单倍群的起源和分布，小东西们是搞了不少小动作的。 这个问题不可能那么容易瞒天过海，海内外关于人类基因溯源和分布的研究如火如荼，稍微用心用 …

2017年2月7日 · We analyzed 47 fully sequenced Y-chromosomes and reconstructed the haplogroup Q3 phylogenetic tree in detail. Haplogroup Q3-L275, derived from the oldest known split within Eurasian/American haplogroup Q, most likely occurred in West or Central Asia in the Upper Paleolithic period.

2016年9月25日 · Y-DNA haplogroup Q arose in Central Asia and migrated through the Altai/Baikal region of northern Eurasia into the Americas. Today it is found in North Eurasia, with some exemplars in European populations. The Q-M3 sub-group is almost exclusively associated with Native American populations. References:

The human Y-chromosome haplogroup Q (also named Q-M242 in accordance with its defining mutation) probably originated in Central Asia and Southern Siberia during the time period of 15–25 KYA (1000 years ago) (Karafet et al. 2002, 2008; Bortolini et al. 2003; Seielstad et al. 2003), then subsequently diffused in the eastward, westward and ...

The Y-chromosome haplogroup Q has three major branches: Q1, Q2, and Q3. Q1 is found in both Asia and the Americas where it accounts for about 90% of indigenous Native American Y-chromosomes; Q2 is found in North and Central Asia; but little is known ...

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] It is home to a vast array of people who belong to diverse ethnic groups, who migrated to the region during different periods of time.

2014年11月9日 · Because of continuing research, the structure of the Y-DNA Haplogroup Tree changes and ISOGG does its best to keep the tree updated with the latest developments in the field. The viewer may observe other versions of the tree on the Web. Email Alice Fairhurst if the differences need clarification or if you find any broken links on this page.

Descendant lineages are identified as people test their Y-DNA with the Big Y test. There are 97 DNA tested descendants, and they specified that their earliest known origins are from Russian Federation, Saudi Arabia, Hungary, and 29 other countries. This information is self-reported by FamilyTreeDNA participants.

S1 Fig: Geographical distribution of the sub-lineages Q-MPB139 (A), Q-Z5908 (B), and Q-B42 (C). Colored circles represent the geographic distribution and sub-lineage membership, as shown in the inset tree. The size of the circles is related to the number of subjects and is specified with the "n" in the box to the right, see S1 Table.

2017年9月7日 · The human Y-chromosome has proven to be a powerful tool for tracing the paternal history of human populations and genealogical ancestors. The human Y-chromosome haplogroup Q is the most frequent haplogroup in the Americas. Previous studies have traced the origin of haplogroup Q to the region around Central Asia and Southern Siberia.

To delve further into this issue, we examined more than 400 Native American Y chromosomes (collected in the region ranging from Mexico to South America) belonging to haplogroup Q – virtually the only branch of the Y phylogeny observed in modern-day Amerindians of Central and South America – together with 27 from Mongolia and Kamchatka.
