Dr. Henry Outlaw discusses the basic structure of DNA during a lecture Saturday morning at the Lee County Library about DNA and how it can be used in genealogy research. (LAUREN WOOD | DAILY JOURNAL) <\/p>\n
But now that research doesnt need to stop. Dr. Henry Outlaw, retired Delta State University chemistry department chairman and genealogy hobbyist, said that is when DNA can become helpful. <\/p>\n
There are many companies that test DNA and store it in databases for people interested in tracing their lineage. <\/p>\n
DNA testing became a tool for use in genealogy in about 2000, Outlaw told the North Mississippi Historical and Genealogical Society on Saturday morning at the Lee County Library. There are many test types and many competing testing laboratories. The trick is knowing what each test means. If you take the wrong test, youll get the wrong results. <\/p>\n
Outlaw said his goal was to help the society understand the terminology of DNA testing so they could use the testing services in an informed way. <\/p>\n
The DNA testing services send a swab the tester will use to scrape cells out of his or her mouth and then mail back. Once the service tests the swab, the company will send back results and store the testers DNA, with permission. <\/p>\n
Of the many companies available, Outlaw said he uses FamilyTreeDNA.com because of its larger database. <\/p>\n
The companies can compare a persons DNA with whats in their databases and show relatives as well as distant ancestry. <\/p>\n
The most popular test, Outlaw said, is a Y-DNA test that shows male relatives that share a common relative in the testers paternal line. <\/p>\n
