I'm a little puzzled by this. I don't know whether this is an assumption of our culture or not. But as far as science is concerned, I believe the standard assumption of research comparing MZ and DZ twins is that MZ and DZ twins are treated similarly. This is the "equal environments assumption", sometimes challenged but more often accepted in the field. Stephen ______________________________ Stephen L.
