Many questions remain relevant to the biology and management of the reproductive system in mammals. What do you consider to be an important topic of research? Justify your argument. Identify a target species. Describe a specific gap in our knowledge – how would you address the issue/solve the problem? The name of the class is Principle of Mammalian Reproduction, we covered a lot of aspects on reproduction, fertilization, hormone, miscarriage, immunology and endocrinology etc. I will probably have to relate this paper to class materials.
