Well if you only have to mate with one of the other 2 genders, then what's the point of having 3? It completely defeats the purpose, because that means only 33% of the population can fertalize, and 66% of the population can't fuck each other. This also means only 66% of the race is guaranteed to reproduce, while 33% are bound to go sexless. True you still have a substantial birth rate, but it'd be nothing compared to that of a race of two genders, where 100% of the population can mate, not including infertile members. A race of 2 genders can effectively double the population or more so per cycle, the only check and balance being the Death Rate versus the Birthrate. Not to mention the population will grow exponentially faster than that of a 3 gender race, where one gender is effective useless by the way you describe it. It'd only make sense if all 3 were required to produce a child, in which case I again point to the fact that a 2 gender race would be more effecient because it'd be 2:1 where as a 3 gender race would be 3:1
