Synthesis is the central means/mechanism of reproduction. There's no opposition. Rather, it indicates your misuse of the term - and the others you are throwing around. You have now eliminated the last shred of possible meaning from your use of that word. Bollocks. They'd never reproduce if they did that. They don't. They produce things describable using such sequences, often, but no known plant uses numbers at all. Now we have restrictions "causal to" inabilities. My point, above, that a convenient simplification or shorthand notion such as "cause" is not useful for careful analysis in these matters, is well illustrated.
