Strange. It's very unusual for twins to inherit so remarkably different features. It's already unusual enough for a child to inherit fair skin and hair colour if the other parent has a dark skin/hair, and the chances that twins would turn out so different are very, very slim (as they. Are you sure the kids were not adopted?
Anyways, I dislike
Ebony and
Ivory as a twin set. I don't like the names, I think the set is too themey, and I actually find it quite shallow that they were given names so obviously connected to the colours of their skin (which is also way I dislike names like
Blondie or
Ginger, unless they're nicknames). The only thing I like about the set is that the names were kind of flipped around instead of the obvious way. That adds a little spunk to the set.
