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.
