Fascinating PBS documentary a few weeks ago on the 'epigenetic' system -
that environmental events during an individual's life, while they don't
change the structure of the genome, have a direct impact on the expression
of genes, and that these changes are passed down (via their effect on
formation of eggs and sperm) to the next generation, and even to
grandchildren. If my grandfather lived in a time of famine, my likelihood of
developing diabetes is much increased. As David says, something can be
heritable but not genetic (in origin). The inheritance of acquired
characteristics, no less.
