Female are in purple, males are in blue. M1 is initial egg for females, M20 is initial eggs for males, M10 is for both. Just like usual, the female carry a stemocyte with S2 input, the male have +S2 secrocyte. After being fertilized, the stemocyte will channel to another stemocyte that will randomize its offspring gender via +-S1. But heres the catch: The males are unattracted to females.
So, what if the male gets really scarce?. I managed to found a little trick when making my Pseudo Races, the unfertilized egg will 90/10 split to a female egg!

I followed wikipedia on Parthogenesis, when the female gave birth to another female without fertilization. Its possible to produce both gender in cell lab though, by making the stemocyte split 90/10 to the gender stemocyte instead of the female egg
