- (20 points) Using information provided on pages 2457-2458, discuss:
- what epigenetics is and why it is thought to be important
- what are the primary mechanisms involved in epigenetic inheritance
- what sorts of cellular changes may occur as a result of epigenetics
- (20 points) Referring to page 2458, discuss how epigenetics might have evolutionary influences.
- (20 points) Also on page 2458, there is a discussion of intrauterine exposures and how that might affect the fetuss phenotype. What are some known exposures that affect the fetus in this way?
- (20 points) Referring to page 2459, discuss how/why genomic imprinting may be the strongest evidence for transgenerational epigenetic inheritance.
- (10 points) On pages 2462-2463, summarize the main points of the authors discussion and conclusions. Does transgenerational epigenetic inheritance exist? What might be some limitations of studying this in humans?
- (10 points) Using the RMU Library database system, find a primary literature article that is related to this topic. Provide the full citation for this article as the answer to this question.
