The elephant in the room

1. Would first need to know what is meant here by epigenetics.

   Non-heritable traits (“variants, that return to normal in time”)? Would not be on my priority research list for a genebank.

   Or is it Lamarckian theory? “A set of mechanisms that allows plants to adapt to their environment” (example: sterile flowers in oil palm???). “And why don’t their progenies have any recollection of this?”. Goodness.

   Or just plain phenotypic variation. “In that case, why do plants exposed to the cold or to heat modify the expression of their genome?”

   All of the above?

   I wonder how much is known about phenotypic variation among different genotypes of a crop.
