DNAPrint Presents at 55th Annual AAFS Meeting Friday February 21, 12:58 pm ET SARASOTA, Fla., Feb. 21 /PRNewswire-FirstCall/ -- DNAPrint (OTC Bulletin Board: DNAP - News; the "Company"), the world leader in the measurement of population structure for disease genetics, personalized medicine, forensics profiling and consumer genomics, has presented at the 55th Annual Meeting for the American Association of Forensic Scientists. Zach Gaskin presented the Company's DNAWitness suite of physical profiling products to the world's leading forensics laboratory directors and scientists. Several hundred CD-ROMs detailing validation and challenges to the suite were distributed. The focus was on the Company's Ancestry 2.0 test, which is a forensics version of the company's successful recreational product, AncestrybyDNA 2.0. Both tests measure Ancestry Informative Markers (AIMs) across the genome in order to determine the proportionality of biogeographical ancestry (BGA) within individuals. The measurement of BGA admixture proportions is useful for forensic scientists who desire to reconstruct a partial physical profile from crime scene DNA. The AAFS meeting is being held February 17-22, 2003, in Chicago, IL. The response to the presentation was overwhelming and during the first two days of the conference, DNAPrint's booth was one of the most popular at the show.
