Nyf's Genetics
by Nyfaria
Nyf's Genetics adds genetic traits to mobs and villagers, and breeding passes those traits from parent to offspring through a Punnett square.
What it does
Breeding is the only way to obtain the mutation options. Each pairing is set up on a Punnett square, and mutations can occur by chance in the offspring, so the result of a breeding is not fixed by the parents alone.
The mod applies them to the vanilla mobs and to villagers, which carry seven traits, with more options planned for later updates.
Installation requires Fabric API on Fabric. Servers that run it need every player to install it too. Builds are published for Fabric and Forge for 1.20.1, and the mod is released under All rights reserved, so it is not open source.
Key features
Genetically modified mobs
Vanilla mobs receive genetic traits that can be inherited and altered through breeding.
Appearance traits
Visible traits such as eyebrow shape, eye tint, hair style, hair shade, nose dimensions and skin tone are inherited through the genetic system.
Villager traits
Villagers carry seven traits, with additional options planned for future updates.
Punnett square breeding
Breeding follows a Punnett square setup in which mutations can appear by chance in the offspring.

Use cases
Breeding projects
Players who breed mobs can track how traits pass from one generation to the next.
Villager variety
Villagers in a town show different appearances, since each one carries its own set of traits.
Who it’s for: Players who want mob breeding to change how animals look, and server owners who want villagers to vary in appearance. Because the mod runs on both sides, a server must install it along with every client that joins.
