I am copying information from Family Tree DNA on the 25 marker upgrade below. Yes, I believe your dna signature which was the bottom one on the chart I sent you would be very appropriate in a book about your family. Evelyn Mitchell Smith, whose father's dna matched yours is very anxious to communicate with you and try to see where your families come together. I hope you can help one another. Aneita PRODUCTS PROJECTS TESTIMONIALS PRIVACY FAQ ABOUT HISTORY UNEARTHED DAILY Genealogy by genetics is the greatest addition to Genealogy since the creation of the Family Tree! Understanding and ordering the 25-marker test Over the course of the last year, as the Family Tree DNA's genetic database has begun to mature, we have noticed that certain groups of people - especially in family re-construction projects - have enjoyed numerous exact matches (12/12). Most of our clients are Western European, and Western Europe was settled relatively recently by a very limited Y-DNA gene pool, so it is understandable that use of a limited number of markers is likely to provide true genetic matches from a time BEFORE surnames were adopted. Considering that the primary purpose of genealogy is to link with relatives - ideally, relatives that we can draw some version of a paper trail around - FTDNA is now bringing to the market a much higher resolution test that will contract the time estimates to the Most Recent Common Ancestor (MRCA)- see chart. Who should order Y-DNAPlus? This refinement of our existing 12-marker test offers the following advantages: - Substantial reduction in the Most Likely Estimate (MLE) to the MRCA. - Constriction of the tail of the curve to a time frame that approximates the adoption of the surname by families in the British Isles. - An invaluable aid for Family Re-Construction projects who have found 11/12 or 12/12 matches and now want to gain a better snapshot of the actual breakdown of the family tree. For example we suggest that all of our Re-Construction projects start with our 12 marker test, and come back and refine only those that match at least 11/12 within their group. Should new customers order the new 25-marker test? Now you have a choice, 12 or 25 markers. Both tests prove the same basic question: are we related? However the parameters of WHEN are superior with Y-DNAPlus. We anticipate that the 25-marker format will allow us to answer other interesting Genetic Genealogy questions in the future. Because the University of Arizona (which has the laboratory that we use) keeps the DNA on file in a locked refrigerator, if you decide to start with a 12-marker test, you may return to our site and upgrade your test at any time in the future. | top | | affiliates program | Family Tree DNA - Genealogy by Genetics, Ltd.
