Gene expression is dependent on incredible amount of variables. It'd be a cosmic level of coincidence to have two clones express the same way. That never happens even in single-cell organisms, much less something as complex as fish or human.

"Genes as blueprint" is something that has entered the common knowledge.

At least, it needs to be tempered and modified in the common knowledge by what we have learned "recently" about epigenetics.

And realistically it needs to be modified by everything we don't know too.

I don’t disagree.
