A Trait gene is a genetic modification in Jurassic World Evolution that can be applied to dinosaurs to increase one or more of their in-game traits. Unique genes or gene stages are unlocked on every island. The Secrets of Dr. Wu DLC added additional Trait Genes.

Description

Trait Genes come in a variety of forms and can all be applied to all dinosaurs. All genes, aside from the default Null Gene, will lower a dinosaur’s viability percentage resulting in the possibility of a failed incubation. Most genes have different stages with increased effects that can be unlocked on different islands.

List of trait genes

Base game

NULL Gene

NULL Gene is the default trait gene in Evolution. NULL genes from the American bullfrog (Rana catesbeiana) are carefully chosen to stitch together gaps in genomes, while minimizing overall effects on development.
