This widespread distribution strongly suggests that haplogroup “J1” was part of the Neolithic spread of agriculture into Europe from the Near East beginning approximately 10,000 years ago. Halpogroup “J1c3” is projected to have first appeared in about 7000 BCE and Haplogroup “J1c3b” appeared between about 4500 BCE and 400 AD in Ireland. The 23andMe Test Results report my maternal haplogroup as J2a1a1b. This can be analysed with the data here: PhyloTree.org - mtDNA tree Build 16 Going through the haplogroup tree, one SNP at a time, the haplogroup can be determined. Below are my SNPs that have been confirmed by a SNP test.
Haplogroup I1 (Y-DNA) represents one of the two branches of Haplogroup I (Y-DNA) as defined by the International Society of Genetic Genealogy (ISOGG) Y-DNA Haplogroup Tree 2010 .
