A code allows you to decode something. Knowing the eye-signal gene allows
you to spot other eye-signals - but gives you no idea what any other gene
does. With the genetic code, by contrast, I can give you the amino acid
sequence of any gene, including ones I've never seen before.

Developmental morphology, metabolism enzymes, promoter recognizer, etc. genes - the ones for which such claims are made - are functionally the same in us, fruit flies, nematodes, and chimps. Your eye-signal gene can't differentiate you from a chimp because it's not different in any functional sense. A human who had all the highly conserved genes from a chimp would be a human to all tests, except to a sequencing machine.
