Haplogroup I-M253

In human genetics, Haplogroup I-M253 is a Y chromosome haplogroup which occurs at greatest frequency in Fenno-Scandia. The mutations identified with Haplogroup I-M253 (Y-DNA) are M253, M307, P30, and P40. These are known as single nucleotide polymorphisms (SNPs). It is a subclade of Haplogroup I named Haplogroup I1 (according to the 2016 classification). Before a reclassification in 2008, the group was known as Haplogroup I1a.
