Also covered are breeding systems and breeding methods.

Breeding Methods includes: inbreeding, outcrossing, and linebreeding.

Breeding Systems explains the different style of putting breeding rats together such as: harem breeding, colony breeding, and monogamous pairing.

We also includes an explanation of what differentiates a "line" as well as what defines a "strain".
