In the original PHP prototype of SnailLife there exists a very rudimentary genetics system. Snails had what I called “visual traits” and “functional traits”. Visual traits had genes associated with them. The genes were all stored in the snail’s table and each gene had two “alleles”. During breeding I’d make virtual Punnett Squares of sorts to pass on genes from parents to offspring. But the system was inflexible - each allele for each gene and each gene type were hard coded in the snails table. This left little room for surprise emergent behaviour (ie is it possible for a snail to accidentally get more or fewer variations of a gene than expected? I’m not sure, but I want a system to support that) without having to modify db columns).
