Haplogroup R2
What is Maternal Haplogroup R2?
Haplogroup R2 is a genealogical group of lineages defined by unique genetic markers present in your mitochondrial DNA, which is transmitted from your mother. Your maternal haplogroup paints a picture of your ancient origins and the migrations of your ancestors. Although your maternal haplogroup reflects just one of your many ancestral lineages, it carries information about that lineage over tens of thousands of years.
Haplogroup R2 is descended from haplogroup R. Among 23andMe research participants, haplogroup R2 is commonly found among populations in Iran, the United Kingdom and Pakistan.
It's important to note that your haplogroup doesn't define your current ethnic identity; rather, it provides an insight into your deep ancestry on the maternal side.

Haplogroup R2 is linked to many people of Europe and Asia
Most of Europe's most common haplogroups, including H, J, T, V and U, are offshoots of R. Some, like U, were involved in some of the earliest migrations to Europe, while others spread from the Middle East with the dawn of agriculture. These groups spread east as well, reaching Central Asia and India first with early farmers and then with Iron Age migrants. In East Asia, R gave rise to the dominant haplogroups F and B. Members of just one branch of B, B2, migrated from Siberia to the Americas after the peak of the Ice Age 18,000 years ago, where their descendants are found today. However, no other branches of R have been found in the indigenous people of North and South America.
Members of haplogroup R, and the astounding works they've created, can be found on nearly every continent.
