My DNA Test came back showing 7% uncertain. Question: If several of my possible 4th cousins on the list also show a particular percentage of "uncertain" on their DNA test results does this mean or could this mean that "their" uncertain could be the same specific small trace as mine (that's also too low to pinpoint), for example: mediterranean coast?)- for lack of a better example...--in other words, could my cousins DNA UNCERTAIN be of the same origin as MINE?? and how would "MORE GENETIC SIGNATURES" be discovered? Is this something you do in the lab AS more DNA tests are taken in "specific" families?? Please advise. I would appreciate NOT receiving the same answers from the script page regarding "Uncertain" that you have & I have because I've read it many times over. I believe that for what it costs to get an analysis that a better explanation would seem quite appropriate. SPECIFIC GENETIC POPULATION, SMALL TRACES and PROBABILITY LEVELS are all confusing DNA terms when all are included in the same dynamics of a short paragraph... Thanks!
