Haplogroup I-M253 is present in all populations, with higher frequencies in the east and lower frequencies in the west. There appears to be no discrete boundary as observed by Weale et al. (2002) In 2003 a paper was published by Christian Capelli and colleagues which supported, but modified, the conclusions of Weale and colleagues. [ 60 ]
PCA and genetic distances of Uralic-speaking populations [1] Genetic studies on Sami is the genetic research that have been carried out on the Sami people. The Sami languages belong to the Uralic languages family of Eurasia. Siberian origins are still visible in the Sámi, Finns and other populations of the Finno-Ugric language family.
v. t. e. A haplotype is a group of alleles in an organism that are inherited together from a single parent, [1][2] 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.

Haplogroup I is a human mitochondrial DNA (mtDNA) haplogroup. It is believed to have originated about 21,000 years ago, during the Last Glacial Maximum (LGM) period in West Asia ( (Olivieri 2013); Terreros 2011; Fernandes 2012). The haplogroup is unusual in that it is now widely distributed geographically, but is common in only a few small ...
Haplogroup I (M170) is a Y-chromosome DNA haplogroup. It is a subgroup of haplogroup IJ, which itself is a derivative of the haplogroup IJK. Subclades I1 and I2 can be found in most present-day European populations, with peaks in some Northern European and Southeastern European countries. Haplogroup I most likely arose in Europe, [1][2] with it ...
Haplogroup I-M253 (I1) at 4,3% of which L22, Z58 and Z63. According to a study published in 2010, I-M253 originated between 3,170 and 5,000 years ago, in Chalcolithic Europe. [44] A 2014 study in Hungary uncovered remains of two individuals from the Linear Pottery culture, one of whom was found to have carried the M253 SNP which defines ...
Genetic studies of Jews are part of the population genetics discipline and are used to analyze the ancestry of Jewish populations, complementing research in other fields such as history, linguistics, archaeology, and paleontology. These studies investigate the origins of various Jewish ethnic divisions. In particular, they examine whether there ...
Genetic genealogy. In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by specific mutations in the non- recombining portions of DNA on the male-specific Y chromosome (Y-DNA). Individuals within a haplogroup share similar numbers of short tandem repeats (STRs) and single-nucleotide polymorphisms (SNPs). [2]
