How to upload your DNA data to Gedmatch
Here are links to some how-to slides I’ve made up for registering and uploading your DNA data to Gedmatch.
Here is an interesting opinion piece from the ABC about whether the Y-chromosome will become redundant and what that means for ‘men’
The Y-Chromosome is Disappearing
Here is a new tool to explore that helps you to map DNA segments to your ancestors. It’s only in beta at the moment but looks promising:
When I get a new match show up on my One-to-Many list on Gedmatch, which shows up highlighted in green, I always check the new match using the User Lookup function. User Lookup is a very useful function, but many people don’t know about this handy tool. You can find User Lookup on your Gedmatch homepage under the “Learn More” heading on the left side of the page. When you click on the User Lookup link, you will open a new page showing choices of filling in the Gedmatch kit number, the Gedcom ID number or the email address. Instead of putting in the Gedmatch kit number of my new match, I cut and paste the email address on the new match instead. Using the email address will give you a list of all the kits that are attached to that email and also provide a link to any family tree (gedcom) that has been uploaded. It is a quick and handy way of finding more information about your new match.
It is most unfortunate to read a review of Family Tree DNA by a popular young American genealogy blogger, Heather Collins, that is full of misunderstandings about how to use DNA and how to use Family Tree DNA itself. The review criticises the absence of features that are actually available; for example, it is possible to download a spreadsheet of all segments from the chromosome browser. The reviewer criticises the functionality of the chromosome browser as a tool, but does not understand how to use it. It would seem that Heather also has very little understanding of the value of Y-DNA and mtDNA testing as important specialised tests, which she incorrectly suggests are ‘niche’, ‘nostalgic’ and ‘from back in the day when these tests were all the rage’. The comments on the admixture also show a considerable lack of understanding about the limitations of ethnicity results at any of the testing companies. Finally, the comment about using AncestryDNA simply because of the larger database ignores the motivations of the people who have tested with each of those two companies: quantity does not equate with quality.
Whilst I think that DNA has been a wonderful catalyst for encouraging younger people to become actively engaged in genealogy and family history, this kind of misinformation spread by a popular young blogger is very disappointing.
Garrett Hellenthal, statistical geneticist at the Genetic Institute, University College London, gave a very interesting talk at the recent Who Do You Think You Are convention in England on the science of how DNA companies predict ethnicity. Given that ethnicity is the main reason why the majority of clients get their DNA tested at AncestryDNA, it is a very good overview of just how the different DNA testing companies arrive at their ethnicity conclusions.
Gedmatch is now accepting links to WikiTree, which shows up in the new Ged/Wiki column. This is a welcome alternative to uploading a gedcom, which needs to be deleted and reuploaded each time changes are made to the gedcom, because it allows the tree to be continuously updated in the WikiTree community and always the latest version will be available in the link.
