From Wikipedia, the free encyclopedia

In human genetics, Haplogroup I is a human mitochondrial DNA (mtDNA) haplogroup.

Haplogroup I is found throughout Europe, and also in Egypt and Arabia. It is believed to have arisen somewhere in Eurasia some 30,000 years before present, and been one of the first haplogroups to move into Europe.

Its ancestral haplogroup was Haplogroup N.
