Americans are roughly 28% to 35%, which is higher than their overall average autosomal European ancestry of about 16% to 20%. [1, 2]

Why the Difference Exists
- Sex-Biased Gene Flow: Historical genetic studies, such as research published in PubMed, show that the American slavery era involved asymmetric or sex-biased reproduction. [1, 2, 3]
- Paternal vs. Maternal Lines: Enslaved African women's maternal lineages (mitochondrial DNA) were largely preserved, while European men disproportionately contributed to the paternal lines (Y-DNA). [1]
