Your friends Sue and Tom have been trying unsuccessfully to have a baby. Their doctor wants to pursue in vitro fertilization but the entire process, including harvesting oocytes and sperm, can be expensive, time-consuming, invasive, and problem-laden. Sue has heard that cloning uses various typ of cells and knows that you're studying biology, so she wants to know whether skin cells from Tom could be used to fertilize skin cells of hers, rather than using eggs and sperm. What do you tell Sue about the cells needed for reproduction so that she thoroughly understands why certain cells are needed?
