TEST YOUR ETHNIC MAKEUP Have you always suspected there's some Native American ancestry in your family tree, but you don't have the documentation to prove it? A DNA test from a company in Sarasota, Fla., provides measurements of a person's racial ancestry and ancestral proportions. DNAPrint Genomics offers a do-it-yourself test you can order on its Web site http://www.dnaprint.com. A test costs $290 regularly or $160 as part of an introductory special offer. Simply swab the inside of your cheek, and DNAPrint will determine your racial mix. Scientists at DNAPrint look at a set of genetic markers that can tell a lot about a person's continent of origin. Looking at differences in genetic variations among populations helps them to determine a customer's racial makeup. Visit the Web site for details.
