In addition to the excellent GEDMatch site, if you are willing to spend the time to watch the YouTube clips and learn how to use it, Genome Match Pro is a brilliant program that takes the whole autosomal DNA matching to another level.

RE: Question regarding the DNA feature in Legacy Dear Legacy users who are interested in DNA tests for genetic matches: Counter-Point to Cathy’s response to Crystal and other Legacy users who have autosomal DNA test results: It’s simply not useful or practicable for anyone to place Mb of autosomal DNA raw data into a Legacy event, since it would not serve any purpose (that I can see) to use for comparing DNA-sequence matches, because Legacy and its integrated FamilySearch database do not yet support autosomal DNA tests to evaluate possible genetic relationships; i.e., 1. I participated in the mentioned AncestryDNA webinar hosted by Geoff and (not an insult, just factual) a not-so-expert colleague, where they viewed his AncestryDNA autosomal results; however, (as stated above) Legacy and FamilySearch do not support autosomal DNA test results yet, so this webinar was not very practical for most Legacy users, and it had only partial rudimentary information that most AncestryDNA users (except brand-new novices) would perhaps find useful, which is more clearly and completely discussed in AncestryDNA tutorials and at other better DNA analyses websites. 2. AncestryDNA is very limited and a relatively poor DNA analyses service, since it has no genetic analyses tools (like chromosome browsers offered by other DNA analyses websites), and it uses fixed undefined genetic matching algorithms that have resulted in highly variable results with potential matches over short time periods. For example, I have 4 family members’ autosomal DNA results at AncestryDNA, which have changed dramatically or even totally eliminated valid associations with close relatives’ “Circles” (~ triangulated genetic matches of 3 or more closer relatives); this is most likely due to AncestryDNA’s undocumented subjective changes in math algorithms used to report autosomal DNA sequence matches due to more restrictive and conservative criteria (which tend to omit valid genetic matches, such as previously appeared in many of my prior Circles of close family units). 3. Experienced DNA analysts often report, and I fully agree from long and broad experiences for multiple reasons, that the best current website to use for autosomal DNA evaluations is GEDmatch.com; FamilyTreeDNA.com is usually considered second best, 23andMe.com follows, then a newcomer is MyHeritage.com with fairly good autosomal DNA matching and a huge European database of family trees, and AncestryDNA is in last place for helping to best determine genetic matches from autosomal DNA results. The main reasons for this ranking of usefulness and relative success are: * GEDmatch has many powerful DNA analyses tools, where you can match either or both your uploaded autosomal DNA results (GEDmatch does not provide testing services, just good DNA analyses) and/or your family tree relationships that you upload for FREE from a GEDcom file; their chromosomal browser and graphical presentations of results with clear definitions are excellent, and they allow you (with appropriate explanations, caveats and warnings) to customize selection criteria for genetic matches that can really help determine if you and a particular individual share DNA sequences in the same segments of a specific chromosome, or not – very valuable tool, along with the 2-D and 3-D chromosomal browser graphics and simple matrix reports plus detailed triangulation tools and much more. Maybe this sounds complicated, but GEDmatch makes it quite easy to use and understand what you are doing and why and what it means in terms of potential genetic matches; again, a stark contrast from NO such tools or similar information provided by the meager AncestryDNA. * FTDNA costs $39 to upload your autosomal DNA, and they have some good DNA analytical tools – especially their Family Finder and a chromosome browser; they are sponsored by National Geographic, and they now offer the most affordable autosomal DNA tests at $59 during December (else the tests cost $99) * MyHeritage just began to let members upload autosomal DNA for FREE, and they contract with FTDNA to analyze and report potential matches back to members in their family trees; however, they have no tools to conduct more detailed genetic match evaluations * 23andMe has a good long reputation, but has focused more on specialized and less informative tests (to use for genetic matching of closer relatives) such as Y-DNA, X-DNA, and mt-DNA that have more specific and narrower uses that some genealogists and researchers use; FTDNA also has emphasized these specialized non-autosomal testing, and only in recent years have autosomal DNA test results been able to be used more successfully to help identify potential relatives vs non-relatives (lab methods and math formulas to report autosomal DNA results continually change) * AncestryDNA has had the cheapest autosomal DNA test prices for several years of ~$89-99, until FTDNA’s holiday offer this month for $59 vs $99 normally; however, AncestryDNA has no DNA analyses tools and relatively naïve support staff, plus most importantly is that their genetic match results and demographic origins are not very consistent or accurate (changing over short times, relatively large margins of accepted errors in results vs other DNA testing services, etc.) I wish and am waiting for Legacy and FamlySearch to incorporate autosomal DNA test results into their databases and software to help match up closer relatives, which I hoped the soon-to-be-released LegacyDeluxe v9 might support; LegacyDeluxe v8 has existing data-entry fields for non-autosomal DNA results, of mostly “haplo-groups” derived from Y- and X- or mitochondrial-DNA tests, mostly supported for older DNA analytical service companies that are becoming out-dated or have gone out of business (as far as I can tell, when checking out their websites). Current Bottom-Line: anyone wanting to get the best value and productive results from their autosomal DNA tests should import them into GEDmatch.com and FamilyTreeDNA.com, where you can also upload your GEDcom files with family tree information and then use customized searching to better evaluate potential genetic matches; you’ll be amazed at how much more and better autosomal DNA information can be readily obtained for free or low cost at these websites (vs uncertain and frustratingly questionable matches reported by AncestryDNA) – remember, FTDNA has its autosomal DNA tests on sale for $59.

The results are quite different and can't be entered in the way that the listed DNA results can be. They're several MB rather than a few lines. Note that Legacy Webinars have lots of webinars on DNA including very useful ones on understanding the Ancestry Autosomal test results in the Watch Geoff Live series where he sits with an expert when first looking at his results. You'll need a subscription to watch http://familytreewebinars.com/dna Cathy Crystal Payne wrote: I have just found the DNA icon and was reading up on the attachment of my dna to my Legacy file. I noticed that Legacy does not list the Autosomal DNA test. Is there another test listed that is comparable to the autosomal test? Is the autoso mal test results not qualified or sufficient to use in Legacy? Should we wait for Legacy to add this test? Thank you and I apologize if I have overlooked the answer in the help files, etc. Crystal
