[BUB] Gender
by be_bub
[BUB] Gender gives each mob a random gender on spawn, and that gender decides whether the animal can breed, which items it accepts and whether it is sterile.
What it does
Mobs are assigned a gender when they spawn, with the chance of each gender set in the config between 0% and 50%. Infertile mobs cannot breed, and the breeding chance follows the configured male to female ratio. Same-gender breeding can be blocked, or sterile breeding can be turned off so that pairs breed without restriction. Villagers receive a gender too, and the gender is kept when a zombie villager is cured.
The mod scans modded animals that extend the Animal class and adds them automatically. Any other animal can be added by hand in the config. Some mods need manual configuration to get a correct gender split, and the list of mods already configured is part of the documentation. Gender rules can be set for specific items, such as stopping a male cow from being milked.
The mod runs on Forge and NeoForge for 1.20.1 and 1.21.1, and the server and every player need it. It is released under the MIT License and is open source, and its source code, issue tracker and wiki are public. Files were first published on 2026-03-28 and last updated on 2026-07-05, and the interface is available in English, Deutsch, Español and Français.
