ItemDescription
Y Note: There are currently no Ancestry items for the letter Y
Did You Know: Because DNA contains information that has been passed down relatively unchanged from early ancestors, analysis of DNA is sometimes used for genealogical research.
Two DNA types are of particular interest:
- Mitochondrial DNA that we all possess and that is passed down with only minor mutations through the matrilinial (direct female) line;
- The Y-chromosome, present only in males, which is passed down with only minor mutations through the patrilinial (direct male) line.
