any theory of sex is incomplete until it addresses why there are 2 sexes (even if one organizm can carry both sexual organs it is still 2 distinct sexes). It may seems obvious, yet a science theory must address it scientifically. All the shuffling, flushing, etc.. of genes would also work in 3, 4, ... sexes schemas. It will have different statistical distributions and the theory must prove that whatever goal of sex existence, it is somehow optimal with 2.

Why not have any two humans mate to have offspring? there are 23 pairs of chromosomes and only 1 pair is sex determining. doesn't really make sense to have male/female especially since the 'male' physical characteristics are small enough to be present in a female also.
