If I am remembering correct, the Genesis DLC is the Genesis digital comic, which serves as a means of establishing some background about the universe you will be playing in. When importing a character, you will not experience the Genesis digital comic because the universe has already been established. Are you importing an ME2 character that was imported from ME1 or a character that you created for ME2 from scratch where you used the Genesis digital comic to establish the background? In the former case, you shouldn't encounter the DLC. However, I've never tried the latter, so I don't know. Also, in the 5 or so hours since you posted your question, it is likely you've already found out for yourself. You should reply to inform what happened! I'm actually pretty interested.
