- A human blastocyst normally implants in ................. a. an oviduct c. the uterus b. a seminiferous tubule d. the vaginaIn a possible future scenario, male fertility drops to zero, but, luckily, scientists develop a way for women to pro-duce babies by virgin birth. Meiocytes are converted di-rectly (without undergoing meiosis) into zygotes, which implant in the usual way. What would be the short- andlong-term effects in such a society?Why do you think asexual reproduction is more common in animals like flatworms and sponges than in vertebrates ?
