I don't know about human/vampire hybrids, like most. But if they're anything like animal hybrids, ligers, tigons, then there's a very high chance Renesmee's infertle. With animal hybrids there's always more from 1 side. So let's say Nessie's has a little mroe vampire in her than human, she probably couldn't have kids. If she has more human in her than vampire, she probably could have kids. It all just comes down to which traits she got from which parent.
