Y-DNA
• The male line of testing. The direct
line because only males pass on the
Y-Chromosome. Useful in surname
studies in verifying and validating
surname genealogies.
Direct male line 338,000 years
Mitochondrial DNA Testing
Direct female line 200,000 years
We inherit our mitochondrial DNA, mtDNA, from our mother, and
none from our father. Females pass on the mtDNA, males receive
mtDNA ; but do not pass it on to next generation.

Ancestry.com is an autosomal test and has certain
parameters which must be understood.
1. Need on-line tree to connect to other trees
2. DNA test must be linked to that tree
3. Useful if tree is public
4. Does not generate “circles” unless public
5. Raw data can be exported to www.gedmatch.com
Ethnic Origins
• Notes on Ethnic Origins
• Derived from comparing to DNA of people in
their reference panel.
• Not all companies use same panel
• Not all companies use same country labels i.e.,
Ireland is incorporated as part of Great Britian
• View with “grain of salt” Interesting but of little
value.
• Does have some value in reconstructing a DNA
sample for someone who never took a DNA test

10 Do’s and Don’t of DNA Testing
• 1. Do not take any DNA test without first
trying to put together your family tree
• 2. After you get your DNA results, respond to
your messages.
• 3. If you chose to make your tree private in
Ancestry, at least be willing to invite others to
view upon request
• 4. Try to understand the basics of DNA
• 5. Show your family tree
• 6. If you have a family tree, include exact locations,
i.e., city, county, state.
• 7. Don’t list just two surnames in your profile.
Adoptees are exempt from this
• 8. Don’t leave your profile blank in 23 and me and
FamilytreeDNA
• 9. Upload to GEDMatch—all sources, Ancestry,
Familytreedna and 23 and me. Gedmatch has
chromosome browing tools that Ancestry does not
have.
• 10. Have patience with Gedmatch. It is a free DNA
utility and often over capacity.
Need to Know Very Little
