Just bang one of the 2 other genders and make a kid. What's complicated about that?

Of course 1 is the most efficient, but my theory is still more efficient than 2. So by your logic 2 is less believeable.

The problem with 3 is evolution. Although my theory should make evolution potentially more efficient as it expands options for passing genes, evolving from asexual organisms to species with 2 genders in the first place is much more simple than evolving into 3, otherwise zooologists would've already already discovered a species that has 3 by now.
