Genotype begins focusing on the preservation and purification of the rat race and brand, steering away from its original medical focus. A flaw in the Rat species’ coding and anti-mutt protocol threatens to muddle all the various breeds of rat into a homogeneous single species.

Genotype becomes associated with, and soon dominated by, the Rat species.
