If they are fraternal twins they *don't* have the same genes, that's why the statement is misleading.

I meant similar Genes, like siblings would have. However, it is possible that they are monozygotic twins because the only thing I noticed really different was the hair color, could just be dyed (which usually happens with identical twins as they want to differentiate themselves). Either way, my point was I got the point of the statement which was to say the two sisters were polar opposites.
