The four sperms for each primary spermatocyte are produced through spermatogenesis, but oogenesis produces only one egg for each primary oocyte. The reasons for these different outcomes that they might be adaptive. Introduction: Gametogenesis is a process by which haploid gametes are formed. The sperm and ovum are the male and female gametes, respectively, formed with the help of processes called spermatogenesis and oogenesis, respectively. The haploid gametes are formed from diploid germ cells. Spermatogenesis occurs in the seminiferous tubules of the testis and oogenesis occurs in the outermost layer of the ovaries.

Which of the following statements does NOT correctly describe the similarities and differences between male and female reproductive systems? Select one: a. Millions of mature sperm are produced on a daily basis, whereas single mature ovum is released every 28 days. b. Meiosis is completed in eggs after fertilization begins, whereas a mature sperm has completed meiosis prior to fertilization. c. Eggs and sperm contain exactly half of the genetic material of a normal somatic cell. Many zygotes with an abnormal number of genetic material often do not successfully implant. d. Eggs and sperm can survive for 3 to 5 days in the Fallopian tubes.
