-- more times:

1. Roll to find the nucleotide to mutate.
2. Depending on the roll:
   • If the roll is between 1 through 18, inclusive, select that nucleotide.
   • Otherwise, skip mutation and clone the genome again.
3. Roll to see what kind of mutation to perform.
4. Depending on the roll:
   • If the roll is between 1 through 14, inclusive, perform a transition on the selected nucleotide.
   • If the roll is between 15 through 17, inclusive, perform a complementing transversion on the selected nucleotide to the base it pairs with.
   • Otherwise, perform the other transversion on the selected nucleotide.
5. Select the correct amino acid for the new codon.
6. Depending on the change to the codon:
   • If the mutation caused a change in the amino acid being coded, then kill it and start again with the previous generation.
   • Otherwise, clone this genome for the next generation.
