1.
a) Briefly describe the biological mechanism of epigenetic influences, including how they interact with our DNA and why that interaction is important. (5 pts)
(b) Describe two important ways that we discussed in which the biological mechanism of epigenetics differs from that of genetics. (3 pts each)
(c) If evolution drives genetics, what drives epigenetics?
2. Although we have yet to find the precise biological mechanisms of variation in gender identity and sexual orientation, briefly describe why the influence of prenatal sex hormones will likely prove to play a dominant role. Be sure to include how these hormones affect tissue development other than sexual organs (5 pts), the primary and secondary effects of these hormones (5 pts), and why the concept of critical periods is so important
