БЪЛГАРИ- ГЕНЕТИЧЕН АНАЛИЗ - ПОСЛЕДНИ НАЙ-ТОЧНИ ИЗЧИСЛЕНИЯ
HG1 - 17%
HG2 - 42%
HG3 - 12%
HG9 - 12 %
HG21 - 17%
HG1- 17% КЕЛТИ
R1b (previously known as Hg1 and Eu18) is the most prolific haplogroup in Europe and its frequency changes in a cline from west (where it reaches a saturation point of almost 100% in areas of Western Ireland) to east (where it becomes uncommon in parts of Eastern Europe and virtually disappears beyond the Middle East). A R1b haplotype (a set of marker scores indicative of the haplogroup) is very difficult to interpret in that they are found at relatively high frequency in the areas where the Anglo - Saxon and Danish "invaders" originally called home (e.g., 55% in Friesland), and even up to 30% in Norway. Thus a R1b haplotype makes it very challenging to determine the origin of a family with this DNA signature.
HG2- 42% ТРАКИ
The members of HG2 are believed to be the descendants of two later waves of humans into Europe. The last of these waves arrived about 8,000 years ago and is credited with introducing agriculture into Europe. HG2 is most common in Southern and Central Europe, but that haplogroup is also often seen in those of Anglo-Saxon and Scandinavian descent.
HG3- 12%СЛАВЯНИ
"The distribution of HG 3 chromosomes is also strongly clinal, but with a very different axis and more on a regional scale.... It reaches its highest frequencies in central-eastern Europe, comprising approximately half of the chromosomes in the Russian, Polish, and Slovakian samples; frequencies in the southeast and southwest are low. This distribution resembles the third principal component of variation of classical gene frequencies, which has been interpreted by some geneticists (Cavalli-Sforza et al. 1994) as marking the movement, from north of the Caspian Sea, of the Kurgan people, dated to ~7,000 YBP."
HG9 - 12% ПРАБЪЛГАРИ
HG 9, defined by the 12f2 deletion, is largely confined to caucasoid populations, with its highest frequencies being found in Middle Eastern populations.
In Iranian populations, HG 9 shows very high frequencies (30%60%). Populations from the southeastern Caspian region and the Zagros Mountains exhibit the highest frequencies so far observed (60%). High frequencies of HG 9 have been found throughout the Fertile Crescent region (Hammer et al. 2000): Palestinians, 51%; Lebanese, 46%; and Syrians, 57%. The incidences of HG 9 in Pakistan (18%) and northern India (19%) indicate a decreasing-frequency cline from Iran toward India.
HG21 -17% ПЕЛАСГИ
North African HG21 (Y-chromosome), as well as J, T1, U3 and certain H and W subclusters (mtDNA). Note the uneven distribution of these below, with paternal ancestry differing greatly between SE and SW Europeans despite close racial ties, and maternal ancestry being higher in N and C Europeans than in S Europeans.
