Gedmatch:. Are your parents related

No, the northern french side of my mother is located in a specific town.

My parents are both from the same Finnish region, but in Finland cousin marriages were banned for hundreds years. So I am a bit confused about what my results means. Neither Gedmatch gives answers, only results and I don't know how reliable these results are. I hope people could post results here. We have no real world evidence that children born of cousin marriages are vulnerable to diseases or something bad, although claims of that are usual, especially in America where many see Europe as a more inbred place. Disease carriers are another question and based on rare mutations, which of course are forwarded to children. Here is my result:

One segment.
Largest segment = 10.8 cM
Total of segments > 7 cM = 10.8 cM

Can you check random dozen of Finns? If most of them happen to have common segment it would be confirmation of inbreeding theory.

I could try, but I have other activities today and tomorrow. Selecting random 1000g samples it would be possible. Maybe ten samples. I made a while ago a homozygote run test using Beagle and there was nothing proving about inbreeding. Beagle uses genome adresses in Morgans as also this Gedmatch test. The old fashion homozygote run test counts only SNP runs, giving false results near centromeres. Runs near centromere can be thousands years old.

I know my parents are distantly related and they both came from a small town, I dont' have their DNA though, it would have a been fun.

Largest segment = 0 cM
Total of segments > 7 cM = 0 cM

No shared DNA segments found

This analysis indicates that your parents are probably not related within recent generations.

Not surprising for me.

My both parents are half Dalmatian islanders, and islanders are said to be inbred but luckily I'm not at all.

I do wonder whether people with 100% paper trail ancestry from Krk island would have a different result. I know that Y-haplogroup percentages are peculiar among them so some kind of founder effect definitely is there.

My point was that people shouldn't push all negative attributes to Central or Eastern Turks, I know enough Turks from everywhere of Turkey with marriages among relatives. My father is a Central Anatolian Turk who didn't married a relative, who is not even from somewhere in the proximity of his village.
