Before reading this post, you should know how to read a kitty’s genes.
Each trait in CryptoKitties has a “mutation pair” that, when bred together, gives a small chance (usually 14%) of generating a brand new trait not necessarily seen in either parent. Those new traits are referred to as mutations. After a gene mutates, it may then be passed on to offspring the same way as basic traits.
Because Gen 0 cats only have basic traits, mutations tend to be rare at low generations, so they are often (but not always) more valuable.
(Note: Mutations are separate from the “recessive” genes that have a chance to gene swap into the dominant position.)
How do mutations work?
From a technical point-of-view, mutations occur when pairs of neighboring genes (e.g. 00010 & 00011) are bred together. If they mutate, the mutation takes the gene with a ‘1’ at the end and moves it to the beginning (e.g. 00011 –> 10001). You don’t really need to know that, though. You can just use the following method.
In the chart below, you can see that topaz and mintgreen are a neighboring pair. In the right-hand column, it says they mutate into gene ‘i’. Find ‘i’ in the kai column and trace it back to eye color. Topaz and mintgreen have the potential to mutate into limegreen.
