Is not that something which is done only in African countries, so couples can be sure their children won't suffer from adnormalities on their red cells?
This is something which is pretty much unheard of in the American continent, I have never had my blood examined when I have a girlfriend and I have never even suggested any of my girlfriends to get tested to know their genotypes...

It must be kind of weird to live in a society where people pays such amount of attention to genetics of other people. Again, it is something which is not common here.
