Most pairs ignore gender; a few special rules require specific sexes and change the child with direction.

Normal pairs

Example: Penking + Bushi → Sibelyx. Swapping parent order keeps the species; gender usually does not matter.

Gender dual example

Female Katress + male Wixen → Katress Ignis; male Katress + female Wixen → Wixen Noct. The calculator errors when genders fail a rule instead of inventing a species.

How to use the tool

Set parent A/B sexes before calculating. For all parents of a form, use reverse search and watch gender markers on results.
