In more recent studies it's been shown that (and I may be wrong in the exact ratio but I recall it being pretty close) 1 in 4 people actually have more than just two (XX or XY) quite a few people have three and in some cases it's been documented up to five chromosomes. Just figured I would throw that in as I found it very interesting...carry on.
I didn't think that it was as high as 1/4 but it is definitely not as unusual as people think.
