Mitochondrial DNA (mtDNA, the DNA located in mitochondria, different from the DNA in the nucleus of a cell) and Y-chromosome DNA are commonly used to trace ancestry in this manner. mtDNA is generally passed un-mixed from mothers to children of both sexes, along the maternal line, or matrilineally.

DNA Solutions offers the analysis of mitochondrial DNA (mtDNA); whilst only inherited maternally, mtDNA is found in both men and women.
