Genetic Testing
by Maltshakes
Genetic Testing, by Maltshakes, adds gene testing for animals on Forge, with modules for color, body proportion and production genes.
What it does
Genetic Testing is an add-on for Genetic Animals that lets players run gene tests on animals. Testing covers Genetic Bettas, and separate modules check color genes, body proportion genes and production genes. Each module can be switched on or off in the config, and when a server runs a config, that server config takes priority over the local one.
Animals keep enough recorded data for the mod to pull an entire family tree. The add-on also works with the vanilla book, letting players receive records of the results. Other animals with similar genetic tests are covered by mods such as Realistic Horse Genetics, and the wiki lists the genes each animal carries in more detail.
Genetic Testing is published for Forge only, across six release versions 1.20.1 – 1.20.6, and the latest file is 0.1.2-1.20.1 for 1.20.6. The server and every player need the mod installed. The main mod can be used freely in single-player worlds and on servers, and it is released under All rights reserved, so it is not open source.
Key features
Color gene testing
A dedicated module tests the color genes an animal carries, and the results are kept with its records.
Body proportion testing
A module checks body proportion genes, giving a second set of results alongside color.
Production gene testing
A module checks production genes, so breeders can compare results across several traits.
Family tree records
Animals store enough data for the mod to reconstruct their whole family tree from recorded parents.

What the author says
An add-on mod for the Genetic Animals mod that allows you to use a vanilla book to receive a record of the various genes the animal possesses, similar to genetic tests you would see in mods like Realistic Horse Genetics or Simply Cats. This is an optional tool for people - while it won't be present in the main mod…
