    3. Hi, If you access the Family Tree DNA Lab, they have enough independent material references to satisfy anyone regarding DNA usage for any purposes. I jsut do not think that most of the DNA labs used by genealogy researchers are just trying to sell a product. The one thing that DNA doesn't do is lie. If your DNA (FTDNA uses upto 37 markers) matches another person's DNA in 37 of 37 markers, no matter what else is false, the truth is that you and that person are descended from one individual in the not too distant past. Of course it doesn't tell you who that person is but absolutely gives you the direction in which to search. As an aside, let us say that the infamous Zodiac killer's DNA yields readable Y chromosome from which the FTDNA defined 37 markers could be obtained, and they matched mine, then you could with no doubts say that the Zodiac killer was a Walker. It would tell you his surname and that he and I are closely kin and also that I could POSSIBLY be the Zodiac but it would not point unambiguously to the individual. For that, they would need more DNA markers but just which ones they would be I have no idea. Finally, no matter how you slice it, Y Chromosome DNA testing can be a very worthwhile tool and it was worth every penny I paid for it since I was one of those who had a number of close matches in the group. However, for the unexpected number who had NO close matches, it has to be a HUGE disappointment. That fact can point to several possibilities, most of which are not comforting. The first is that none of his close relatives have joined yet, next, he may have been adopted, kidnapped, or whatever, and last and worst, his mommy may have played around on his daddy. If I were one of those, I would compare my DNA results with every other surname DNA group. If I found a group in which there were one or more individuals matching me closely, that would tell me who my actual ancesters were (but not their name, of course). As with anything else there are upsides and downsides. Lannie List Administrator wrote: > Scott researchers, > > (Comments?
