Caucasus hunter-gatherer (CHG), also called Satsurblia cluster, [1] [2] is an anatomically modern human genetic lineage, first identified in a 2015 study, [3] [1] based on the population genetics of several modern Western Eurasian (European, Caucasian and Near Eastern) populations.
The table below lists the frequencies – identified by major studies – of various haplogroups amongst selected ethnic groups from the Caucasus. The first two columns list the ethnic and linguistic affiliations of the individuals studied, the third column gives the sample size studied, and the other columns give the percentage of the ...
The genetic history of the Middle East is the subject of research within the fields of human population genomics, archaeogenetics and Middle Eastern studies.Researchers use Y-DNA, mtDNA, and other autosomal DNA tests to identify the genetic history of ancient and modern populations of Egypt, Persia, Mesopotamia, Anatolia, Arabia, the Levant, and other areas.
A genealogical DNA test is a DNA-based genetic test used in genetic genealogy that looks at specific locations of a person's genome in order to find or verify ancestral genealogical relationships, or (with lower reliability) to estimate the ethnic mixture of an individual. Since different testing companies use different ethnic reference groups ...
Y chromosome haplogroup distribution of Turkish people [4]. A 2021 study which looked at whole genomes and whole-exomes of 3,362 Turkish people found that the most common Y chromosome haplogroups were J2a, R1b, and R1a (18.4%, 14.9%, and 12.1% respectively).
It appears to be most frequent and diverse in the Western Caucasus, so an origin there has been suggested, while its subclade H5a appears European. [5] However, samples of mtDNA with T16304C in the HVR1 region have been found in four individuals of around 6800 BC from the Pre-Pottery Neolithic B site of Tell Halula , Syria , [ 6 ] suggesting ...
There are two distinctive mapping approaches used in the field of genome mapping: genetic maps (also known as linkage maps) [7] and physical maps. [3] While both maps are a collection of genetic markers and gene loci, [8] genetic maps' distances are based on the genetic linkage information, while physical maps use actual physical distances usually measured in number of base pairs.
DNA evidence suggests that during the Last Glacial Maximum, a period between 25,000 and 19,000 years ago, large ice sheets over a kilometer thick covered much of Northern Europe, making the region uninhabitable to humans. It is believed that human populations retreated south to warmer regions near the Mediterranean.
