matriline

This term is primarily used in technical, academic contexts such as anthropology, sociology, and genetics. It describes a specific structural lineage, contrasting with a patriline, which traces descent through males. The term carries a neutral, descriptive tone and is rarely used in casual conversation unless discussing genealogy or kinship systems.

In biological and genetic research, the term often refers specifically to mitochondrial DNA inheritance, as mitochondria are passed from mother to offspring. This creates a distinct biological marker that allows researchers to track ancestral migrations and population histories over thousands of years.
