Sep 24, 2020 population genetics often use haplogroups, which are branches on the tree of early human migrations and genetic evolution.
A haplotype is a group of alleles in an organism that are inherited together from a single parent, and a haplogroup ( haploid from the greek: ἁπλοῦς, haploûs, onefold, simple and english: group) is a group of similar haplotypes that share a common ancestor with a single-nucleotide polymorphism mutation. More specifically, a haplogroup is a combination of alleles at different chromosomal regions that are closely linked and that tend to be inherited together.
In the study of molecular evolution, a haplogroup is a large group of haplotypes, which are series of alleles at specific locations on a chromosome. In human genetics, the haplogroups most commonly studied are y-chromosome (y-dna) haplogroups and mitochondrial dna (mtdna) haplogroups, both of which can be used to define genetic populations. Y-dna has the advantage of being passed solely along the patrilineal line, while mtdna is passed solely on the matrilineal line.
1 u1 evolution occurs when heritable characteristics of a species change.
From the standpoint of population studies, there are 3 main widely used groups of polymorphic dna markers: 1) mutations of mitochondrial dna (mtdna), transmitted only through the maternal lines; 2) str and snp markers of y-chromosome, inherited only by paternal line; 3) autosomal markers, available for the analysis of maternal and paternal inputs.
They can be highly polymorphic and are frequently used as molecular markers in population genetics studies.
A total of 1214 y chromosomes, positive for e haplogroups, were considered in the analysis.
The tree is explained in the review article the human y chromosome: an evolutionary marker comes of age by jobling and tyler-smith, and more recent findings on various branches are collected in the tree posted by the international society of genetic genealogy whit athey's haplogroup predictor, which predicts haplogroup from str data.
Haplogroup c3c has been identified as a possible marker of the aisin gioro ( who were founders of qing dynasty) and is found in ten different ethnic minorities in northern china, but completely absent from han chinese.
Haplogroup g-fgc7535, also known as haplogroup g2a1 (and formerly g-l293), is a y-chromosome haplogroup. It is an immediate descendant of g2a (g-p15), which is a primary branch of haplogroup g2 (p287).
Haplogroup (hg) classifications are based on different y chromosome markers (snps) than those used in surname studies (strs). Snp markers mutate much more slowly than strs and are used by population geneticists to identify groups of people over thousands of years. In other words, haplogroups link one to a common paternal ancestor far back in time - to one's deep ancestry.
Haplogroup p: this rare haplogroup, defined by m45 and 92r7 among other markers, probably arose in northern eurasia, possibly siberia, and soon gave origin to two sister haplogroups much more successful: q, that encompass with the q3 sub-clade almost the totality of the amerindian (not na-dene) y-chromosomes, and r, that is the most frequent.
So it is no surprise that they did not have just one genetic marker, to judge by their descendants. If and when scientists find ancient y-dna from men that we can guess spoke proto-germanic, it is most likely to be a mixture of i1, r1a1a, r1b-p312 and r1b-u106, to name only the most common haplogroups.
Moreover, high-resolution analysis of y chromosome haplogroup q has allowed the evolutionary y-str mutation rate place the origin of this marker at around.
Identifying your haplogroup can tell you a surprising amount about your deep ancestry. They are generally associated with particular geographic regions and can tell us about our ancestor's migration routes out of africa, as well as linking you to a group of people who share ancient ancestors.
The majority of 60 mtdna markers are polymorphic in southern shaanxi han population. The most common haplogroups observed in southern shaanxi han population are b5, followed by d5, a, d4e, and n9a1'3. Obtained matching probability for these 60 mtdna markers indicates that the panel could be used as a valuable tool in forensic caseworks.
There are two kinds of haplogroups: the paternally inherited y-chromosome dna (y-dna) haplogroups, and the maternally inherited mitochondrial dna (mtdna) haplogroups. They respectively indicate the agnatic (or patrilineal) and cognatic (or matrilineal) ancestry.

A group of related haplotypes, or, casually, the group of people who carry those haplotypes. Because haplotypes are composed of dna markers, which are inherited, haplogroups are formed as a result of related lineages sharing a common ancestor in which all those markers were first found. A prediction or confirmation that determines to which haplogroup a person belongs, done by assessing their dna markers.

The primary frisian y-dna haplogroup is the r1b subclade called u106/s21, defined by its mutations u106 (and l48) and negative for p312. It's coded by family tree dna as haplogroup r1b1b2a1a its subclades include r1a1b1b2a1a1, r1a1b1b2a1a2, r1a1b1b2a1a3, and r1a1b1b2a1a4.
Haplogroups as evolutionary markers of cognitive ability abstract: studies investigating evolutionary theories on the origins of national differences in intelligence have been criticized on the basis that both national cognitive ability measures and supposedly evolutionarily informative proxies (such as latitude and climate) are confounded with general developmental status.
The y haplogroup classification of the male y-chromosome is currently used to estimate the population group of the paternal line. Haplogroups are subdivided into one or more levels, called subclades, and thus forming a tree.
Haplogroups enable the most basic level of phylogenetic assignment of humans into populations on the basis of shared paternal or maternal ancestry and hence phylogeographic origin. Such haplogroup analysis has been used to trace african origins and subsequent major migration routes for all anatomically modern humans on the planet.

For example, haplogroup e is african, but within haplogroup e, there are two major divisions with very different stories for their clans. One group is found only in sub-saharan african and one is found mostly in the middle east and the mediterranean basin and is known colloquially as the berber haplogroup.

More specifically, a haplogroup is a combination of alleles at different chromosomal regions that are closely linked and that tend to be inherited together. As a haplogroup consists of similar haplotypes, it is usually possible to predict a haplogroup from haplotypes.
The markers p37, m253, m223 of haplogroup i, m81 and m293 of haplogroups e, and m367, m368 and m369 of haplogroup j1 were typed but not observed. A star (*) indicates a paragroup: a group of y chromosomes not defined by any reported phylogenetic downstream mutation.

Haplotypes, which can be defined by the many binary markers and microsatellites that are available, pass down paternal lineages and change only by mutation.

Humans represent one branch of this tree, which was built based on dna and particularly snp markers, which are small changes or mutations in the dna that occur naturally over time.

Each name uses a letter to identify the major branch of the tree and the name of a genetic marker unique to a specific haplogroup. For example, if we previously reported your paternal haplogroup as “q1a3a,” we now report it as “q-m3,” indicating that your y-chromosome lineage belongs to a subgroup of haplogroup q that bears the m3 marker.

Haplogroup information and comparisons between family tree dna information and that at 23andme is not apples and apples. In essence, the haplogroups are not calculated in the same way, and the data at family tree dna is much more extensive. Understanding the differences is key to comparing and understanding results.
The r-m124 mutation represents the defining y-dna marker of the r-m124 haplogroup of the human phylogenetic tree. It is now often referred to as the r2a haplogroup (see sections below for a discussion of current r2a y-dna phylogenetic trees).

Y dna haplogroups e3b, j2 and g belonged to the early farmers that arrived in europe from the middle east, while haplogroup i represents the old farmers. Thus, the i, e3b, g and j haplogroups are some of the oldest y dna genes seen in europe the r subhaplogroups are attributed to repeated ancient human population migrations into europe.

Dogs were the first domesticated species, but the precise timing and location of domestication are hotly debated. Using genomic data from 5,392 dogs, including a global set of 549 village dogs, we find strong evidence that dogs were domesticated in central asia, perhaps near present-day nepal and mongolia.
