OK, but precisely what constitutes an "extragenetic origin"??

Well, there is one sense in which that is true - people typically mean
_genomic_ when they say genetic and the transmission of cytoplasmic genes
is importantly different from that of nuclear genes.  Still, if we are
interested in freeing developmental biology from the grip of
gene-centrism, it doesn't seem to help much to point out that there are
genes all over the cell that are important....

Biologists of the world unite, you have nothing to lose but your genes!
