I'm a twin and I have A pos. blood and I think that my twin has like A neg. I 
was wondering if, in order to be an Identical Twin, you have to have the same 
blood type. When we were born, my doctor thought that we were identical, and so 
we have assumed since then that we are. But we gave blood recently and found 
out that one has pos. and the other has neg. So can we be identical twins or 
was the doctor wrong, and we're frat. twins?
