Abstract. Increasing phylogenetic resolution of the Y chromosome haplogroup tree has led to finer temporal and spatial resolution for studies of human migration. Haplogroup T, initially known as K2 and defined by mutation M70, is found at variable frequencies across West Asia, Africa, and Europe. While several SNPs were recently discovered that ...

The result is a tree of Y chromosomes that shows how all paternal lines are related — called a phylogenetic tree. To see your haplogroup highlighted in a phylogenetic tree, click "Scientific Details" located near the top of the page. At the left edge of the tree is the most recent common paternal-line ancestor (MRCA) of all living people.

Family Tree DNA (FTDNA) in late 2004 published a revision of the YCC-2002 structure. In this new tree, Haplogroup I-M223 was apparently assumed to be P38- and, as such, it was renamed as Haplogroup I2, as shown in Figure 2. Figure 2Haplogroup I According to FTDNA's Proposed Revision of the Y Phylogenetic Tree (simplified for clarity).

Haplogroup A is believed to have arisen in Asia some 30,000-50,000 years before present.Its ancestral haplogroup was Haplogroup N.. Its highest frequencies are among Indigenous peoples of the Americas, its largest overall population is in East Asia, and its greatest variety (which suggests its origin point) is in East Siberia.
Occasional mutations on the Y-chromosome from one generation to another help to distinguish different Y-chromosome lineages. These lineages are grouped into larger groups of lineages called haplogroups. Y-DNA haplogroups most commonly found in Africa include A, B and E, as well as subgroups of other haplogroups.
Until the mutation order of the SNPs is determined, they are referred to as phyloequivalent SNPs, i.e. they are equivalent in that block. In the case of M253, there are even another 309 SNPs (Table 2) that would be eligible for the designation of I1. However, the haplogroup is uniformly named I-M253 in all Y-trees.
sequence data (e.g. M21d, R22) and in those cases we decided to follow the established nomenclature; when less than three complete sequences added a relatively deep-rooting branch to the tree we also found it justified to assign it a haplogroup name (e.g. L1c1a1b, M52). For clarity, all branches that are insufficiently supported by complete
A discrepant Y chromosome haplogroup assignment may mean that a non-paternity event has occurred along the line connecting two paternally related males. To see whether one haplogroup assignment is consistent with another, you can check the phylogenetic tree located in the Scientific Details. If two haplogroup names are found along an unbranched ...
Haplogroup L1 is one of the oldest branches of the maternal family tree, a daughter of the mitochondrial Eve and sister to L0. It is most frequently found in western and central sub-Saharan Africa, and seldom appears in eastern or southern Africa. L1 gave rise to branches L2-L6, with L3 giving rise to all the non-African haplogroups found today.
