Today the new DNA site – DNA.land – did a major update which vastly improved the display page for matching relatives and also got rid of the false matches that we all initially saw.
Personally, I love the concept of crowd sourcing DNA science. This new site, created by a team at Columbia University, promises on its about page that you will “learn more about your dna and contribute to important scientific research.” It is also “in partnership with the National Breast Cancer Coalition (NBCC) to better understand the genetic risks of breast cancer.” So of course I had to try it out. I uploaded the raw DNA data for my Dad, myself, and one aunt in the first day of its operation.
On the day after I uploaded, I was able to look at the matches page. My matches to my Dad and a maternal aunt are shown above. I like the compact display of the chromosomes on the right and was fascinated by the “ancient DNA” concept. An improvement today is to show the longest segment. I find having at least one large segment, more than 20cM, to be an important indicator of a close relative especially when combined with total cM or even better “Total Recent cM.”
As of today you can click under the image to get a table of the actual matching segments. This table was easy to cut and paste to a spreadsheet. Aternatively the whole page can be cut and pasted (Control-A to select, Control-C to copy)
