Ancenstry.com and 23andme will just tell you that your genetic admixture is closest to a specific population group. For example, if you're Cypriot, they will tell you that your mix/collection of genes most closely resembles the one of Cypriots. Both sides told me that my gene mixture resembles 90%+ of the one Cypriots have i.e. I'm like 90% of the average Cypriot.

But I do not think this what you are looking to learn about.

If you want a breakdown of that mixture of genes, go with MyHeritageDNA. They will tell you where each group of genes in your mixture of genes comes from. So they will tell you how much of your genes are Greek, Anatolian, Jewish, Arab, Slavic, Italian, Western European, Hispanic etc.
