Paths of DNA inheritance

From ISOGG Wiki

The paths of DNA inheritance depends on the type of DNA.


Y-DNA and mtDNA (males)

Y-chromosome DNA (Y-DNA) is passed from father to son along an all-male line (highlighted in blue). Mitochondrial DNA (mtDNA) is passed from mother to child along an all-female line (highlighted in pink). Males pass Y-DNA to their sons, but do not pass mtDNA to their children.
