Haplogroup R-M420
What is Paternal Haplogroup R-M420?
Haplogroup R-M420, also known as Haplogroup R-M420 (Y Chromosome Consortium long-form label), is a genealogical group of lineages defined by unique genetic markers present on the Y-chromosome. Your paternal haplogroup, or that of your father if you do not have a Y-chromosome, paints a picture of your ancient origins and the migrations of your ancestors. Although your paternal haplogroup reflects just one of your many ancestral lineages, it carries information about that lineage over tens of thousands of years.
Among 23andMe research participants, haplogroup R-M420 is commonly found among populations in the United Kingdom and Ireland.
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 paternal side.

Haplogroup R-M420 is linked to Mal'Ta Boy
Buried with a variety of trinkets including an ivory crown and stone-hewn figurines, “Mal'Ta Boy” was a freckled three-year-old who lived 24,000 years ago near Lake Baikal in Siberia. Although Mal'Ta Boy's life was cut short by unknown circumstances, his genome contains important clues about the ancestors of modern Native Americans.From Mal'Ta Boy's bone samples, researchers determined that he carried paternal haplogroup R, an ancient lineage that is still relatively common in Western Europe, Central Asia, and South Asia. One striking discovery was that Mal'Ta Boy's genome showed affinities with both modern European and Native American populations, but not with modern East Asians. This suggests present-day Native Americans are likely descended from at least two source populations: one originating in East Asia and the other closely related to Mal'ta boy's Central Siberian roots.
