Human: What are fraternal twins?

Assistant: Fraternal twins are a type of “twin” which come from the same egg splitting into two, but then not fertilizing.  So they’re different “siblings”, and not a pair of twins.  They’re called “fraternal” because it’s like brothers, you know?  Sorry, maybe I’m just talking too much.
