Types of Tests
There are three types of genealogical DNA tests, autosomal (atDNA), mitochondrial DNA (mtDNA), and Y-Chromosome (Y-DNA). Autosomal tests for all ancestry. Y-DNA tests a male along his direct paternal line. mtDNA tests a man or woman along their direct maternal line.
Any of these tests can be used to some degree for recent genealogy or for ethnic ancestry.

And sinks into my throat her tiger’s tooth,
Stealing my breath of life, I will confess
I love this cultured hell that tests my youth!”
