You know one thing I always wonder about these ratio stories is how the hell the population survives. For a species to have a stable population at minimum they need to have a birth average of 2.2. For a population with this large of a gender ratio they would need a birth average of 100.2 meaning that every woman would need to give birth to a hundred children minimum for there to be a stable population. Any species with such large gender ratio would very quickly go extinct unless there is some unique strategy which allows them to make up for it.
