We have a [template](./Common/Defs/RaceGeneDefs/RaceGeneDefs_template.xml) and you can add animals and/or genes from mods there (Racegroups are base-rjw).
One of the main motivations was to have genes being added to the xenotypes that other mods and the base game add, e.g. adding demonic penis for impids.
4. Alpha Genes "Female / Male Only" Genes might overwrite later Genitalia-Changes and should be avoided in combination with RJW-Genes features.
5. rjw.sexperience.cumgenes removes fertilin-gain from Cum item - I hope I addressed this by adding a load order but keep me posted (Issue #41)
6. [Consistent Gene Inheritance](https://steamcommunity.com/sharedfiles/filedetails/?id=2881479142&searchtext=Consistent+Gene+Inheritance) alters inheritance - it messes a bit with the Insect-Caste Logic. Your game will not crash, but the insect xenotypes will be a bit messed up.
