How can intergenerational change effect epigenetic change?
• Dutch hunger winter studies – grandchildren of the women pregnant during the famine still showed effects of the famine.
• Born small – small uterus constrains growth of next fetus• Female eggs in a woman’s ovaries formed and start
developing when she is still a fetus – thus grandmothers environment shapes early development
• Mitochondrial DNA – responsible for making some of the proteins essential for the energy maintenance of all cells comes solely from the maternal line via the mitochondria in the egg, and not via the sperm
(DNA transmitted directly from the grandmother to the granddaughter – grandchildren can’t control the
availability of food in their environment but they can be induced to alter their metabolism to make the best use of it)–
