Haplogroup I-M253, also known as I1, is a Y chromosome haplogroup. The genetic markers confirmed as identifying I-M253 are the SNPs M253,M307.2/P203.2, M450/S109, P30, P40, L64, L75, L80, L81, L118, L121/S62, L123, L124/S64, L125/S65, L157.1, L186, and L187. [7] It is a primary branch of Haplogroup I-M170 (I*).

With a 95% probability, the most recent common ancestor of all members of haplogroup I-M253 was born between the years 3266 and 2028 BCE. The most likely estimate is 2606 BCE , rounded to 2600 BCE .

Haplogroup I1 is the most common type of haplogroup I in northern Europe. It is found mostly in Scandinavia and Finland, where it typically represent over 35% of the Y chromosomes. Associated with the Norse ethnicity, I1 is found in all places invaded by ancient Germanic tribes and the Vikings.

Dec 30, 2022 · Haplogroup I1, also known as I-M253, has puzzled experts and amateurs alike for a long time. Why was it so rare prior to the Nordic Bronze Age? How did it become the dominant Y-DNA haplogroup in Scandinavia?

Jul 24, 2022 · Haplogroup I1, also known as I-M253, has puzzled experts and amateurs alike for a long time. Why was it so rare prior to the Nordic Bronze Age? How did it become the dominant Y-DNA haplogroup in Scandinavia? Is it native to Scandinavia, or did it …

Haplogroup I1 has an estimated time to most recent common ancestor around 4000 to 5000 years, and the haplogroup is commonly denoted as I-M253, where M253 being one of the 300 SNP mutations defining the haplogroup.

From my own punching in of your numbers I get I1-M253-ML and I1-M253-AS9a, at varying percentages everytime but that is normal. http://www.isogg.org/tree/ISOGG_HapgrpI.html , the new ISOGG Haplogroup I tree.

I1-M253 et al has highest frequency in Scandinavia, Iceland, and northwest Europe. In Britain, haplogroup I1-M253 et al is often used as a marker for "invaders," Viking or Anglo-Saxon. The I1b-M227 subclade is concentrated in eastern Europe and the Balkans and appears to have arisen in the last one thousand to five thousand years.

Haplogroup I1 (M253) Your Y-chromosome results identify you as a member of haplogroup I1 (M253). The genetic markers that define your ancestral history reach back roughly 60,000 years to the first common marker of all non-African men, M168, and follow your lineage to present day, ending with M253, the defining marker of haplogroup I1 (M253).
