Haplogroup I (Y-DNA)

Haplogroup I (Y-DNA)

In human genetics, Haplogroup I-M170 is a Y-chromosome DNA haplogroup, a subgroup of haplogroup IJ, itself a derivative of Haplogroup IJK. Y-DNA Haplogroup I-M170 is predominantly a European haplogroup today. It represents nearly one-fifth of the population of Europe. It can be found in the majority of present-day European populations. Haplogroup I-M170 Y-chromosomes have also been found among some populations of the Near East, the Caucasus, Northeast Africa and Central Siberia.
