Haplogroup O-CTS701

What is Paternal Haplogroup O-CTS701?

Haplogroup O-CTS701, also known as Haplogroup O-M1359 (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.

Haplogroup O-CTS701 is descended from haplogroup O-M1359. Among 23andMe research participants, haplogroup O-CTS701 is commonly found among populations in China and Taiwan.

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 O-CTS701 is linked to the Han Chinese

Haplogroup O1a is a branch of O-M119, also called O1a. O-M119 and its branches are present in both northern and southern Han Chinese men at low to moderate frequencies, but are most common among the Jiangsu, Shanghai, and Zhejiang southern Han groups. The Han people, who all share the same language and similar cultural practices, are the largest ethnic group in the world, with about 1.2 billion people. Historical evidence shows that Han people are descendants of the ancient Huaxia tribes that come from northern China, and Han language and culture only expanded into southern China in the last 2,000 years. The spread of Han people and culture from northern to southern China was likely driven by warfare and famine in the north. Members of O-M119 belong to a group that has helped to shape the culture of the world's largest ethnic group.
