To be fair, the genome can also clue researchers into biological chemistry that makes it possible to manipulate epigenetic factors or simply find new possible medications that will interact with an unwanted biological situation.

I was especially taken with a recent experiment in which two cohorts of genetically identical fish, one socially dominant and one not, were hybridized with another species and their respective progeny still retained their parents' behavioral attributes.

That's how powerful epigenetic phenomena are. I see it as a "feed forward" element in the system.
