Have you ever wanted to make a kit combining all your DNA tests at the different companies so as to get the most SNPs for comparisons? Well GEDmatch GENESIS is now providing that for paid members. So of course I made one of these superkits for myself! I combined my LivingDNA with my V3 23andme and my current Ancestry kit. Now to investigate what I have gained from this.
The first thing I did was compare this new kit to my recent Ancestry kit. All looked fine. It has the expected small differences, many of which disappeared (including the black lines) when I checked the prevent hard breaks box on the form. The older 23andme kit comparison had more black spots and mismatches.
My next thought about my new superkit was that I might get a better comparison to cousins who tested more recently at 23andme but none of them have uploaded to GENESIS yet. So I checked how my comparison to an Ancestry tester, my second cousin once removed Jeanie, looked. The superkit gets the same result as my recent Ancestry kit. When I compared her to my 23andme kit and my Living DNA kit however, there were small differences.
