There are significant numbers of Jewish men found within multiple subgroups of haplogroup G (Y-DNA). Haplogroup G is found in significantly different percentages within the various Jewish ethnic divisions, ranging from about a third of Moroccan Jews to almost none reported among the Indian, Yemenite and Iranian communities. ==Haplogroup G Subgroups with Jewish Members== The Jewish clusters of men within haplogroup G subgroups often have distinctive shared oddities of values at certain STR markers but sometimes are recognizable by having close genetic distances when dozens of STR marker values are compared. These Jewish clusters are found within all the major haplogroup G subgroups.〔Haplogroup G Project Categories url=https://sites.google.com/site/haplogroupgproject/project-roster〕 G1a -- A cluster of Ashkenazi Jewish men from northeastern Europe is found in G1a persons who are negative for G1a subgroups. These Jewish men share a value of 16 at STR marker DYS19 and 27 at DYS389b. G1a1 -- Another cluster of Ashkenazi Jewish men from northeastern Europe is found in G1a1 persons. So far they seem to comprise the only men who are G1a1, and this is the only known grouping of haplogroup G Jews whose grouping is defined by a SNP mutation. G1c -- A cluster of Ashkenazi Jewish men from northeastern Europe comprises another subgroup, this time within G1c. These Jewish men share an odd value of 12 at STR marker DYS446. G2a1a -- A cluster of Ashkenazi Jewish men from northeastern Europe is found in G2a1a. Almost all differ from the nonJewish G2a1a men in having two distinctive STR marker values: YCA=21,21 and typically DYS19=16. G2a3a -- A cluster of mostly Ashkenazi Jewish men from northeastern Europe is found in G2a3a persons negative for the G2a3a subgroup. Some samples from the western Mediterranean exist which may represent conversos. These men have distinctive values for two STR markers: DYS454=12 and DYS392=12. G2a3b1a -- A number of Ashkenazi Jewish men from northeastern Europe are found within the large number of G2a3b1a men who share the STR marker value of 13 for marker DYS388. These Jewish men lack distinctive STR marker values, but have each other as the nearest matches in comparing STR marker samples. G2a3b1a -- A number of men who share the unusual STR marker values and are otherwise genetically close to each other. This subgroup includes men who may not have known Jewish roots. G2a3b1a1 -- A small group of Ashkenazi Jewish men with ancestral origins in northeastern Europe is found in G2a3b1a1. They share a 12 value for slowly mutating STR marker DYS392, a rarity among G2a3b1a1a1 men. G2a3b1a1a -- A cluster of men whose ancestors were western Mediterranean conversos or had ties to Sephardic Jewish communities is found in G2a3b1a1a. They lack distinctive STR marker values, but have each other as nearest matches in comparing STR marker samples G2a3b1a3a -- A cluster of Ashkenazi Jewish men from northeastern Europe is found within the large number of G2a3b1a men who share the STR marker value of 9 for marker DYS568. These Jewish men have distinctive low marker values at STR marker DYS385a and a high value at DYS385b when compared with other DYS568=9 men. G2b -- A high percentage of G2b men from Europe are Ashkenazi Jewish men who are negative for G2b1. These Jewish men have the distinctive feature within G2b of a shared null value for STR marker DYS425. Based on the number of STR marker mutations seen in comparisons, it is likely the common ancestor of all these men lived sometime in the early Middle Ages. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Jews with Haplogroup G」の詳細全文を読む スポンサード リンク
