Final answer:
The creation of multiple cells during oogenesis ensures the surviving ovum is well-resourced for embryo development, and while the provided options don't directly align, option D most closely refers to the efficiency of the reproductive process.
Step-by-step explanation:
The process of ovulation and fertilization in humans is designed to maximize the chances of producing a viable zygote. During oogenesis, a primary oocyte undergoes meiosis to form a secondary oocyte along with a smaller polar body which eventually breaks down. The purpose of creating these additional cells, which do not survive, is related to ensuring that the egg has enough cytoplasm and nutrients for the development of the potential embryo post-fertilization.
Regarding the options provided in your question, the correct answer is not directly alluded to. However, the production of multiple cells during oogenesis aids in maximizing the resources available to the one surviving ovum, supporting the overall efficiency of the reproductive process. The other cells, known as polar bodies, have minimal contents beyond DNA and do not survive. Therefore, the closest answer aligned with the underlying biological processes appears to be option D, which discusses efficiency and survival but lacks a direct connection to the oogenesis specifics provided.
Internal fertilization enhances the survival rates of offspring and increases genetic diversity. Furthermore, deterrents to polyspermy are critical as multiple sperm fertilizing the oocyte could result in a non-viable triploid organism. Therefore, although option A touches on genetic diversity, it directly relates to the population level rather than the cellular events during oogenesis.
