Listen, and the working bees in the wheat? They don’t give birth to anyone, one uterus would be enough! The ants have the same problem. Even with the same lions, deer and so on.

Or maybe it’s not all that simple? Per it all somehow contributes to the survival of the POPULATION, even without bringing its specific offspring?
