Writing assignment # 2 (100 pts). Due April 27, 2009.

Hormonal control of sex and reproduction in animals

Write an essay on one of the following two topics (3-4 page max, not counting the list of references):

    1. Hormonal control of sex and reproduction: comparison between vertebrates and invertebrates.
    2. Endocrine disruptors in the environment and their effects on hormonal control of sex and reproduction.

You must read at least two (for graduate students - 4) original articles published in peer-reviewed scientific journals on your topic of choice and cite them in your essay. You may also use other sources such as your textbook or Internet sources (be careful about the latter and try to stick to the reliable ones such as books and journal articles). Make sure ALL your sources are cited.
