X&Y DNA.
We all typically inherit 50% of our DNA from our fathers, and 50% from our mothers. And Typically* we are born with 2 sex chromosomes. Everyone inherits an X chromosome from their mothers. Then we inherit our sex determing chromosome from our biological fathers. (Another X, determines female. Y determines male). Y-haplogroups are our paternal inheritance— passed down from direct male ancestors.
