Turner is the founder of the GENEALOGY-DNA mailing list at RootsWeb
and the co-author (with Megan Smolenyak) of
"Trace Your Roots with DNA: Using Genetic Tests to Explore Your Family
Tree." She received her undergraduate degree in biology in 1964 and her
M.D. from Stanford
University in 1970. In
recent years, she developed software for neuropsychological testing and wrote
utility programs for the PAF genealogy program. One of these utilities provided
a way to split out all people in a database who were related via their
mitochondrial DNA, six years before mtDNA tests were commercially available.
The inspiration for this feature came from the (then) forward-looking
predictions of Dr. Thomas Roderick.
