I paid about $100 to get my genome sequenced.
I'm mainly European and mostly of British and Irish extraction.
They report on some 199 chromosome segments - since we all have 46 chromoso mes that's about four segments per chromosome.
About 46 of the segments are labelled European, two more are labelled "broa dly European", another 47 are labelled Northwest European and 38 more are l abelled "broadly Northwest European".
48 are labelled "British and Irish" though the location map showed them cen tered on London and the home countries with some spread up to Manchester an d Merseyside.Eight segments are labelled French and German, though the location map show s them primarily centered on the Netherlands and Belgium, with some spread into southwest Germany centered on Frankfurt am Main.
That's probably from my maternal great-grandmother who was born in Manchest er in 1857 into a family who moved there from Strasbourg around 1850, where they had been rich iron-founders. She had a lot more money than anybody el se in that generation of my family.
Three segments are labelled as Scandinavian and seem to come from Denmark.
One is labelled "broadly East Asian and native American" and two more are l abelled "East Asian and native American". That sort of odd, but seems to co me from my English ancestry - it's at the 0.1% level which could be one ind ividual ten generations back
I also got a huge file - 5.7 Mb zipped - which seems to list some 600,000 s ingle nuclear polymorphisms. My wife got me to dig out the one that predisp oses you to Alzheimer's, if you've got the wrong version. I don't.
Sort of interesting. It was nice to get it documented. One of my nephews se ems to have done the same thing - he hasn't told me about it, but his name showed up on the 23andMe website, identified as my nephew.
