If I'm not mistaken, it's a matri-lineal line. A female is produced (always on the bottom) and a NEW male is introduced to breed with her. BUT they then have to produce a female.

If the current egg turns out to be male it will break the pattern. It won't be ascending anymore. I have a pink female dragon but she can't influence for 2 more days. So I will hide the egg to slow down it's growth rate.
