Maternal and Paternal Haplogroups
Haplogroups are groups of people who share a common ancestor. 23andMe identifies your maternal and paternal haplogroups, providing a glimpse into your deep ancestral roots.
23andMe and Privacy Concerns
Privacy is a major concern for many people considering genetic testing. 23andMe takes several measures to ensure the security of your data, including encryption and anonymization. However, it's important to understand the company's data-sharing policies before signing up.
