[quote=@Hyde] I decided to do it as a foster child and because I genuinely believe there's a chance that my sister and I may not be fully related. I used Ancestry for it, but I don't really think it matters all too much? You can go for either one, I'd say. I haven't gotten my results back and it'll be a couple of week, but I can keep anyone interested in the matter updated. [/quote] Yeah, as someone who is officially a bastard (thanks dad), I can understand that gnawing feeling in the back of your head you might have. I remember there being a bit of a difference, like how 23andme can detect genetic health issues among other things. Though I do think it's just ultimately down to preference, really. And yeah, if you want to drop a note about what you find, sure, I'd hear you out.
