My sister and I had our DNA done through Ancestry, my dna showed a mixed bag of European and Iberia, and some others. My sister's dna came up as 100% France. I got alerted when my sister dna was available and done, and Ancestry said we were closely related. How?

    $\begingroup$ What exactly is your question? How can you and your sister be closely related? Or how come your ancestry results are different even though you are closely related? And an important question here: Are you sharing both of your biological parents? $\endgroup$ – Frieke Jan 10 at 14:15

    $\begingroup$ A general comment: you should not take these geographical ancestry mapping very seriously. There have been a lot of mixing between the different populations of Europe. What is a 100% French? Is there a definition of who is a French? France is a geopolitical entity not a race. This is more of a gimmick that the company uses to make their product popular. Please use your DNA sequencing data to look for more important stuff like susceptibility to diseases. $\endgroup$ – WYSIWYG Jan 10 at 14:15

    $\begingroup$ I'm voting to close this question as off-topic because one cannot possibly discuss the results of commercial DNA tests of individuals without the actual data, and even with the data it would not be appropriate to do so here. $\endgroup$ – David Jan 10 at 14:45
  • $\begingroup$ If I recall there was a good answer on this somewhere that explained how these estimates are done that points out how more or less worthless they are compared to how people interpret them. Like WYSIWYG summarizes, though, this part of your results is really just for entertainment purposes. There are much more direct ways to test your genetic relatedness to a family member. $\endgroup$ – Bryan Krause Jan 10 at 15:26
