genetic lineage
Biological family tree
A genetic lineage is a line of descent traced through DNA, connecting individuals to their biological ancestors.
The term appears in genealogy, population genetics, and evolutionary biology: Genetic lineage testing revealed her ancestors came from West Africa.
Unlike family trees based on names and records, genetic lineage tracks actual biological inheritance across generations.
