Note: The people of Qlaviql have three sexes -- male, female, and muftale. Males are responsible for contributing genetic material and the fertilization "trigger," females contribute the egg cell to be fertilized, along with genetic material, and carry the growing embryo to term. Muftales recieve the infant, and carry and feed it in a belly-pouch for the first year of its life.

Muftale contributions may seem irrelevant, until one realizes that numerous expressions of the genetic information provided by the male and female parents will vary widely depending on the hormones present during the first year of post-gestation. So widely, in fact, that the genes determining sex do not include encoding for muftales -- male or female infants may end up "mufted" during the first year.

One result of this is that the Qlaviqloid "nuclear family" looks more like the roster for a small but very ambisexual dating service. It's easy for guys to get a date, but she's probably your cousin.
