The Dershowitz DNA Project was initiated to augment genealogical research and to provide general insight concerning our family's overall history and genetic composition. DNA testing is not a substitute for genealogy research. Instead, it is a companion tool to prove or disprove research, determine relationships, and to provide clues for further research. DNA testing can be an extremely powerful tool when combined with your genealogy research. DNA testing can uncover information that was not previously known, as well as confirm your research, and get leads for further research. From elementary genetics we learn that the Y-chromosome is passed down through the male line, essentially unchanged, from generation to generation. These chromosomes "mutate" or change slowly over time allowing identification of specific families and surnames. The rate of change is extremely slow, being measured in terms of tens or hundreds of generations. For more family information, blogs, forums, photos and downloads go to the DershSpace website.
