> The genetic combination algorithm is kept seperate so we can open-source all of

> the rest of our code without making it _too_ easy for folks to figure out how the genetics work.

> Don't worry, I'm sure someone will reverse engineer it soon enough!

> -- Commentary from the CryptoKitties source code



**Update 2019**  The sooper-sekretoo GeneScience contract

with the "magic" mixGenes function is now open source

with inline running commentary. Thanks!

> The auctions are

> seperate since their logic is somewhat complex and there's always a risk of subtle bugs. By keeping

> them in their own contracts, we can upgrade them without disrupting the main contract that tracks

> kitty ownership.
