PSYC3338 Study Guide - Midterm Guide: Human Genome Project, Epigenome, Epigenetics
Document Summary
Epigenetics = it is a difference that is not due strictly to genetic changes but to the way we utilize these genes. And so the same process that can cause such a profound difference that one tissue looks like skin and one tissue looks like eye could actually cause less profound changes that result in cancer. But there is so much not known. Key studies: nurtured rats v. neglected rats. Nurturing moms non-cortisol babies become nurturing moms. Switch the pups change the nurturing type. All mother the way we all were mothered children who were born into neglected. Teach her how to be a nurturing mom interrupted the cycle. Changing the nurturing style of the mother. We actually know a whole host of genes. Could be either a genetic basis or epigenetic basis. Effect one twin and not the other the same placenta. One is closer to the placenta than the other? (second one is always getting less?)
