We have repeated the same simulation with about the same numbers
several times, and no matter which numbers we use, one gender ends up
having a lot more individuals than the other, usually by a factor of
about 10. The genders start out equal every time. We also tend to end
up with more grass than there are atoms in the universe, but that is a
statistical fluke. I will check for statistical flukage in our numbers
and try more tests.
