you mean 'asexual', not 'unisexual'. there's no such word as 'unisexual'.

Abe IS male, though, he's just sterile. there's a difference. his pituary and thyroid glands still produce male hormones, he just has no genitals.

also, it isn't all mudokons that are sterile, just the slave caste. we don't know about the sexual status of scrubs, flakes, posers, big kahoonees, or any other castes.

i'd imagine that the difference is quite like the difference between human men and women, except that a slave male and a slave female are both sterile, so wouldn't be able to have babies.

gender is as much a state of mind among mudokon slaves as anything else.
