Haplogroup R1b-S21

Haplogroup R1b-U106, also known as R1b-S21, is a significant subclade of haplogroup R1b, which is widespread in Western Europe. This particular subclade is especially prevalent in Scandinavia and is often associated with the historical and genetic legacy of the Germanic tribes, including the Norse Vikings. R1b-U106 has been found at high frequencies in regions traditionally inhabited by Germanic-speaking populations, such as the Netherlands, Germany, Denmark, and parts of the British Isles, where Norse and Anglo-Saxon influence was historically strong. Genetic studies have linked this haplogroup to the migration and settlement patterns of these groups, highlighting its role in tracing the movement and genetic contributions of Germanic peoples throughout Europe. R1b-U106 is considered a marker for the descendants of these ancient populations, providing insights into the complex tapestry of European ancestry and the influence of early Germanic migrations on modern genetic landscapes. Problem: Haplogroup R1b, which is common in Western Europe, has a specific subclade that is prevalent in Scandinavia. What is this subclade? A) R1b-U106 B) R1b-M269 C) R1b-L21 D) R1b-Z2103
