The answer to my question “There were either twelve sexes or none.” explains that there were actually either five sexes or none.

I remember being confused at the time how DNA would work with multiple sexes, but where did the twelve come from?

Is it possible that in the intervening years I mixed it up with twelve-stranded DNA-like genetic material from the Cheela on Dragon's Egg?
