    3. In response to the original topic, the products offered to American customers are rated this way BY ME: atDNA (autosomal): FTDNA has more scientific tools for Family Finder, by using centiMorgan distance and allowing for a Chromosome browser and matrixing, while Ancestry uses a much more vague definition of relationships. In my opinion, Ancestry and 23andme are more interested in marketing than in the science of genetic genealogy, hence the scads of people on YouTube discussing the "nationality" of their "origins" results, which is based on very scant scientific evidence since "experts" have conflicting theories that are inconvenient for these firms, as well as presenters such as Henry Louis Gates and WDYTYA. White Papers on the subject of migrations, invasions, and prehistoric distribution show that much of the people saying "I am 25% Native American" is pure twaddle. However, many people use all three services for atDNA, since it broadens the pool of looking for matches (Ancestry, FTNDA, 23and me). This is why you will see what looks like "duplicates" on GEDMatch, because users will import ALL of their atDNA results to that service from each individual test company. GEDMatch allows for "phasing" for likely maternal vs paternal shares. The generational distance (time of most recent common ancestor) algorithms on all of the services are also problematic for me, and are taken way too seriously by users who are not old-school genealogists. YDNA: you have no choice but to use FTDNA. It is the only patriline source offered unless you plan to do "genomic" sequencing. Customer Service is extremely variable and communications from FTDNA are about non-existent, but it offers a hosting service for many Projects. mtDNA: never done it, so cannot comment. However, claims of "percentage" of origin locations have a slightly stronger basis from mito ONLY if you know whose definitions are being used (not every scientist agrees with Brian Sykes, just to name one example).

    3. Clinton AncestryDNA actually have a more scientific method for doing the autosomal DNA matching. They are currently the only company who use phasing (a technique for sorting out the DNA letters into the paternal and maternal chromosomes). Without phasing we end up with a large percentage of false positive matches. They've also developed an innovative algorithm for filtering out the high-frequency matching segments which are not genealogically relevant. All the companies strive to improve their matching algorithms. Ancestry will shortly be rolling out improvements to their algorithms. You can find a description here: http://thegeneticgenealogist.com/2016/04/19/ancestrydna-plans-update-to-matc hing-algorithm/ Family Tree DNA are also making improvements to their Family Finder test and those changes should be rolled out very soon too. AncestryDNA try and make the matching process as simple as possible and their shaky leaf hints and DNA Circles can be very helpful, if you're lucky enough to have any. However, they do not provide a chromosome browser so that we can see a visual representation of our matches. I find the chromosome browser to be a very helpful educational tool to help me to understand the DNA inheritance process. The admixture percentages provide by all three companies should be taken with a large pinch of salt. None of the companies are able to distinguish between populations beyond the Continental level (ie, Asian, African and European). There are a couple of exceptions - Finnish and Ashkenazi DNA do show up as distinct population clusters. I wrote a blog post a while back comparing my admixture results across all three companies: http://cruwys.blogspot.co.uk/2015/05/comparing-admixture-results-from.html Best wishes Debbie

    3. Forgot to mention: there is no reason NOT to use GEDMatch, with any atDNA results, it is free for analyzing your results, and they have no dog in the competition between testers. -----Original Message----- From: Clinton Slayton [mailto:[email protected]] Sent: Saturday, April 23, 2016 11:39 AM To: '[email protected]'; '[email protected]' Subject: RE: [G] FTDNA vs Ancestry In response to the original topic, the products offered to American customers are rated this way BY ME: atDNA (autosomal): FTDNA has more scientific tools for Family Finder, by using centiMorgan distance and allowing for a Chromosome browser and matrixing, while Ancestry uses a much more vague definition of relationships.
