The Science of ARK Breeding
ARK: Survival Evolved has one of the most complex breeding systems in gaming. Understanding stat inheritance, mutation mechanics, and imprinting bonuses can mean the difference between a mediocre tame and a devastating boss-killing machine.
How Stat Inheritance Works in ARK
When two creatures breed in ARK, each offspring stat is independently inherited from either the father or the mother with a 55%/45% bias toward the higher stat. This means each stat has a roughly 70% chance of inheriting the better value when one parent has noticeably higher stats.
Our calculator simulates this inheritance model and shows you which parent's stat is more likely to pass down for each attribute, helping you predict the best possible offspring.
Understanding Mutations
Each breeding event has a 2.5% chance per stat of producing a mutation. A mutation adds 2 wild levels to a random stat and changes one of the creature's color regions. Mutations stack, making multi-generational mutation breeding one of the most powerful (and time-consuming) strategies in ARK.
Our calculator tracks mutation counts from both parents and shows you the aggregate mutation chance, so you can plan your breeding lines to maximize mutated offspring.
