genetic relationship
Shared DNA link
A genetic relationship is a connection through biological ancestry—the link between people who share common forebears.
Parents, siblings, and cousins have genetic relationships; stepparents and in-laws do not.
In linguistics, a genetic relationship connects languages descended from a common ancestor: English and German are genetically related through Proto-Germanic.
