I get that O is from 40-50% but even taking AO/BO people is only going to produce another OO 25% of the time. Crossed with an OO it's only 50%. I'm just not making the numbers work for me.
In short, I get the basics of what you're saying but I am not seeing the increase part of it.

I'd have to dig through my notes from those classes and frankly that's not my priority until winter break when I clean crap out. It comes down to a lot of math and looking at birth rates of those with type O blood and their offspring. Like I said it is a long term process, kind of like genetic drift but not really. There is a heavy influence of culture as well, since mobility is increased and the areas where O is closer to 100% people are moving out of and having lots of babies with other O people or passing on O through their non O mates.
If people weren't able to move around things would be explained by the Hardy Weinberg Principle and stay in balance over time, however culture is the changing factor.
