What are haplogroups?
People’s mtDNA test results, depending on which mutations they have, are used to assign them into one of about 20 or so groups (called haplogroups) such that those within each group have similar sets of mutations. In essence, mtDNA haplogroups give an indication of the extremely distant origins of people’s direct maternal lines of ancestry. Brief descriptions for the haplogroups for the Pike project participants is as follows: • H – This is primarily a European haplogroup, and is quite common. About 40% of Europeans are in haplogroup H. • I – This group is primarily a European haplogroup, but is somewhat rare. Only about 5% of Europeans are in this group. • T2 – This is a subgroup of haplogroup T, which is mostly found in western Eurasia. About 10% of Europeans are in haplogroup T. Note that mtDNA haplogroups are different than Y-DNA haplogroups. Both use letters and numbers, but there is no correlation between the two.
Haplogroups are genetic population groups that identify where in the Y-DNA or mtDNA tree of humanity you fit in. Haplogroups are what allow us to identify how large groups of people migrated from Africa around 60,000 years ago to different parts of the world.

Haplogroups are genetic population groups. Mitochondrial haplogroups are composed of people who share a common ancestor on their direct maternal lineage. Your haplogroup tells you what branch on the mitochondrial tree of humanity you belong to. • What is my haplogroup? You will find your haplogroup assignment in the mtDNA Results section of your myFTDNA site. If you took the mtDNA or the mtDNA Plus test then your haplogroup was determined using a panel of twenty-two Single Nucleotide Polymorphisms, SNPs. If you took the mtDNA Full Genomic Sequence, FGS, test then it was determined with your full results. • What are supergroups? Supergroups or macro-haplogroups are the foundation for a number of other haplogroups. They represent older shared ancestors on the maternal tree. They link together many of the more common haplogroups that are found today. • Are mitochondrial haplogroups the same as Y-chromosome haplogroups? No. While they use similar alphanumeric naming systems they are not th
