I used to work in this field, and we would do pedigree analysis a lot on families, usually with some kind of disease.

Anyway, we would construct the family tree, plug it into the stats software and it would tell us: "No. These two people are not cousins, but something closer."

We couldn't ask the families, so we would swap a grandfather for a father, or a mother for a sister, and - hey presto - everything lines up.

This happened in about 1 in 10 families we studied. This type of thing is way waaay more common than people think.

Thanks for sharing. Nice to have less anacdotal evidence.

Well nice is not the right word. But I'm sure you know what I mean,

Less serious posts should go in !casualuk@feddit.uk or !andfinally@feddit.uk
More serious politics should go in !uk_politics@feddit.uk.

Try not to spam the same link to multiple feddit.uk communities.
Pick the most appropriate, and put it there.

Posts should be related to UK-centric news, and should be either a link to a reputable source, or a text post on this community.

Opinion pieces are also allowed, provided they are not misleading/misrepresented/drivel, and have proper sources.

If you think "reputable news source" needs some definition, by all means start a meta thread.

Posts should be manually submitted, not by bot. Link titles should not be editorialised.

Disappointing comments will generally be left to fester in ratio, outright horrible comments will be removed.
Message the mods if you feel something really should be removed, or if a user seems to have a pattern of awful comments.
