In a discussion elsewhere online today, someone said that that black great-great-great-grandma makes me black because "one drop rule", even though everyone in my family looks so white and has identified as white my entire life that if I dared call myself black because of that "one drop" I'd be laughed out of the room by black and white people alike.

I can't make any claims about which has a better database, but pointing to probable ethnic groupings of heritage is not something that requires a terribly complicated set of molecular tools or database queries. The devils in the details, I suppose, regarding specificity of claims, but without sounding too much like Walter from Big Lebowski, "You wanna check for Neanderthal heritage, I can check for Neanderthal heritage, fucking amateurs".


The problem is that they only have their own information to go on, and most of their information is being gathered by self-selecting groups. That is, people who pay for the service.

They're also getting too specific in some cases. Making up shit here, say you're Vietnamese (and all Asian groups have little to no data in places like 23 and Me). You send your shit in and it comes back. You have a marker shared by Western Europeans and one by Northern Europeans. Your chart says France and Norway and because there's limited south-east Asian data, it ignores that people who study genomes have wondered for years how markers that exist in Laos also exist in Western Europe and Northern Europe, but separately.

So instead of "Yeah, you got some Laotian in you, not really a surprise given geographic proximity" you're now wondering what the hell your ancestors got up to in the early 1900s.
This.

And antedote, but I used to be friends with identical twins. *Identical*. their results came back like totally different. Totally. Now yes, there are some variations in monozygotic twins, but I highly doubt enough to give so widely differing results, unless the test is totally flawed. And exactly, they are looking at certain markers. Which is....again flawed when you do not have a proper data set to check against.

I do wonder about the Neanderthal bit though, that addition was interesting. But having my dna on file bothers me for privacy reasons and the whole thing seems a bit a sham anyway.

I think ancestry as in geneology is a more interesting topic...but takes more digging. I know nothing of my father's side except my great grandparents came over from Germany. Based on childhood blip memories, they were the racist nazi kind and frankly I dont care to actually trace them (partially because if they are something extra-terribly-bad...I dont know if I want to know...they treated me like shit, so it wouldn't surprise me). That leaves my mother's side, which has actually been traced back to the 1500's and lost in England records. If I can re-find the name of our ancestor there (the genealogy apparently is hard to get a copy of, I keep trying) I can likely trace further back into the UK/Europe. I know way back past that it goes back to dutch. These are of course just the maternal and paternal, not all the branching. Married into the "main line" is quite a bit of irish, english, dutch, polish, and german (ha, surprise surprise, right?). So basically...white as fuck and everywhere back to Saxons most likely, and I am sure with the long history in America and the racist crap on my father's side I remember, I am sure my ancestors have done a ton of shitty things in the past, and we are in general privileged as fuck likely because of it.

Yay ancestry!

Well, I guess I’ve gotta change my positions on those kits slightly. Because my dad had done one of them, he found out that they’ve got a long-lost half-sister he knew nothing about! She’d been looking for the family of her birth mother — my grandma — and she was able to find them. I still think it’s kind of stupid to be giving a company your genetic information, but now I better understand why people want to use them.

I also agree with this. Sure, my ancestors were from all over the place, but my family has been here for so long it’s not like it means we are anything other than American.

The finding relatives piece is not ridiculous, and I imagine is a large selling point - it is not so difficult these days to identify directly related relatives from DNA. If this technology was widely available 30 years ago, I'm certain a lost of Holocaust survivors would have used it.

I wanna get some dog saliva on a cotton bud and send in to one of these places, to see what they'll say.

They have one for dogs, it has breed markers to determine the likly combo in mixedbreeds....they probably do more dog genetic testing overall than humans.
