Haplogroup I1 is a Y-chromosome haplogroup that is widely associated with the Norse Vikings and is prevalent among Scandinavian populations. It is part of the larger haplogroup I, which is one of the oldest European haplogroups, believed to have originated in Europe around 25,000 years ago. Key characteristics of Haplogroup I1 include: Geographic Distribution: Haplogroup I1 is primarily found in Scandinavia, including Sweden, Denmark, and Norway. It is also present in lower frequencies in other parts of Europe, especially in regions historically affected by Viking migrations, such as the British Isles, Iceland, and parts of Eastern Europe. Historical Significance: The high frequency of Haplogroup I1 in Scandinavia and its presence in areas influenced by the Vikings suggest it was carried by Norse populations during the Viking Age. This haplogroup is often used in genetic studies to trace the movements and influence of Viking settlements. Genetic Diversity: I1 has several subclades (branches), which show different regional patterns and provide insights into the migration and settlement history of ancient European populations. Cultural Associations: Haplogroup I1 is sometimes referred to as the “Viking haplogroup“ due to its strong association with Norse ancestry. It is often highlighted in studies that explore the genetic legacy of the Viking Age and its impact on modern European populations. Ancestral Origins: The origins of Haplogroup I1 can be traced back to the last glacial maximum when ancestral populations lived in refugia in Southern Europe. As the ice sheets retreated, these populations expanded northward, contributing to the genetic makeup of modern Europeans. Overall, Haplogroup I1 provides valuable insights into the genetic history of Scandinavia and the broader impact of Viking migrations across Europe. Problems: Which Y-chromosome haplogroup is commonly found among Scandinavian populations and is associated with the Norse Vikings? A) Haplogroup R1b B) Haplogroup I1 C) Haplogroup J2 D) Haplogroup E1b1b
