Low-pass whole genome sequencing reads your DNA at lower depth to cut costs, then uses imputation to fill in the gaps. Here's how it compares to standard WGS.
Extensive evidence supports the theory that modern humans (Homo sapiens) originated in Africa from genetic, fossil, and archaeological evidence.
Most people with non-African ancestry carry 1% to 4% Neanderthal DNA. We break down which populations carry the most and what 23andMe reports actually tell you.
Freckles are small, concentrated spots of melanin on the skin, most visible on fair complexions. They're linked to the MC1R gene and found in many populations worldwide.
Certain populations have lower genetic diversity than others, often because of historical isolation or population bottlenecks. Here are some commonly cited examples.
Uncles and nephews share about 25% of their DNA on average, but the real number ranges from 17% to 34%. We explain why it varies and what to do when results surprise you.
Italian physical traits reflect the country's long history and regional diversity. These characteristics represent historical averages and stereotypes, not the full picture of modern Italy.
Understanding how your blood type is inherited can feel like opening a family scrapbook written in genes. Yet the story those genes tell is short, and we clarify what blood type can and cannot reveal about your heritage.
Genetics links the first peoples of the Americas to ancient Northeast Asian ancestors, but thousands of years of isolation and mixing made them a distinct population — not simply 'Asians who kept walking.'
Neanderthals averaged 5 ft 5 in to 5 ft 6 in for males, matching pre-industrial Europeans. We explain how scientists measure their height and why the short stereotype is wrong.
