Purpose - DNA data
I am in the process of having my DNA tested. This page will be expanded as I learn.
The DNA testing by FamilyTreeDNA consists of two
separate tests, one for mtDNA the other for Y-DNA. This is how my tests may relate to you.
mtDNA Passed by mothers to all children, only passed by females. Males have
but do not pass mtDNA. If you are related to me through my mother or her sisters or their
mother or her sisters etc etc, then we share the same mtDNA.
Y-DNA Direct male line. Passed from father to son to son etc, never passed
to females. If you are related to me directly through my father or his father or any of their
brothers etc etc, then we share the same Y-DNA.
Lot of ifs. If you fit one of the above then you can use the results.
If we are directly related through my mothers father or my mothers brother or my fathers
mother or my fathers sister then none of the above applies. We are however most certainly
related and I am interested in our shared history. The only real way of finding out, and the
only way to go back before records is a DNA test.
