Indeed - and yet I'd think it's not close at all. I bet there is going to be the same level of variation as compared to relative differences between unrelated humans.
The differences between unrelated newborns would be both genetic & environmental, compared to the identical genetics and nearly identical environments of the twins.
From which point all would begin to diverge further.
