Biology

*Read article 1 and 2, then answer the following questions:

1- Give four (4) examples of environmental chemicals associated with obesogenic properties. For each, speculate on a potential mechanism of action.

Be more specific than the mechanism given in table 1 of Heidel et al. Draw on what you have learned in this class to develop a detailed hypothesis.

2- Describe the mechanism of epigenetic transgenerational inheritance.

3- a) In what ways are the finding in rats relevant to humans? b) In what ways are these finding in rats irrelevant to humans?

4- Develop a hypothesis around how epigenetic modification might effect a) inheritance of obesity, b) inheritance of reproductive disease

Be specific to which types of genes/cellular pathways/developmental processes may be involved
