These happen frequently enough that, excluding a solely maternal lineage, the family tree some generations back is typically not the real tree. You can see the effect here: isogg.org/wiki/… | |

| Apr 12, 2021 at 11:41 | comment | added | S Pr | I think the most help we could offer would be if you narrowed or refocused your question, perhaps after reading up a little about genealogical DNA testing. The wiki entry is more comprehensive than an answer you could expect here. | |
| Apr 12, 2021 at 11:40 | comment | added | S Pr | myheritage.com uses autosomal DNA testing for ethnicity estimate and DNA matching. I assume you went for the latter. I know that different testing companies use different matching algorithms, so some estimates and likenesses for an individual will vary between tests, quite more than one might expect. I think this question is unanswerable in the way that you want; we can't perform an informed calculation for specific regions or genes, but we have no idea which regions myheritage.com uses nor prioritizes, nor with which weight. I hope you can see now that it is probably an intractable question! | |
| Apr 12, 2021 at 10:24 | comment | added | carsten | I didn't know if providing a concrete company name was against the site policies, but I'm happy to provide it. I was using the DNA Test Kit from myheritage.com. | |
| Apr 12, 2021 at 10:04 | comment | added | S Pr | Welcome! I think what renders this question difficult to answer is we don't know what test your commercial company employs. There are very, very many ways to compare DNA between individuals. It's complex: you can share a polymorphic gene variant with a great ape of another species that you wouldn't share with a grandparent, and parts of DNA are inherited paternally/maternally e.g. mitochondrial DNA is used to perform maternal ancestry tracing. To get an accurate picture, ideally one looks through the entire genome. If you provide the company/test name, it might help specify an approximation. | |
