| Y-chromosome Haplogroups |
In addition to your Y-chromosome STR results, we are able to accurately predict which "haplogroup" your Y-chromosome belongs to. Haplogroups can be thought of as branches of the Y-chromosome genetic tree. With its roots in Africa approx. 140,000 years ago, as time has progressed, small mutations have occurred on the Y-chromosome. When a mutation happens (called a SNP, pronounced "snip"), the tree branches so that over time and as people have migrated into different continents and regions, we see a tree-like structure with branches found in certain parts of the world.
Because particular STR patterns are seen within particular haplogroups, on most occasions we can predict which haplogroup you are in and where your Y-chromosome fits into this Y-chromosome tree. Along with the prediction, we also provide the history, background and mapped distribution of your haplogroup.
Please be aware that, whilst our comparative database uses up to date information, it may not be possible to make an accurate prediction on all occasions and sometimes no prediction can be made.
| Your Predicted Haplogroup: G |
Haplogroup G is defined by the SNP marker M201 and considered to be about 14,300 years old. It is observed in high frequency (~30%) and diversity in Georgia within and south of the Caucasus Mountains which would suggest an origin. This haplogroup also has a strong linguistic affiliation to the northwest Caucasian languages, with their paucity of phonemic vowels and rich consonantal sounds. Additionally we detect high frequencies north of the Caucasus in North Ossetia although as there is less haplotype diversity in this northern region it would suggest that only a few founding lineages entered and became successful over time. Upper Paleolithic inhabitants of Weasel Cave in North Ossetia may well have fallen into this haplogroup. This haplogroup is also seen south into Iraq and into Southeastern Europe but almost entirely absent from the rest of Europe.
The haplogroup of G2 (defined by the SNP marker P15) thought to have developed about 12,500 years ago is seen in decreasing frequency from Turkey through to the Mediterranean. Haplogroup G2 is observed at 9% in Turkey and an average of 5% in Italy and Greece. An interesting note is the high occurrence (19%) within the Druze, a small and distinct religious community residing mainly in Lebanon and Israel. This haplogroup is almost absent from the rest of Europe also.
