In vitro fertilization (IVF) is a common assistive reproductive technology for couples who are struggling to conceive naturally; however, the success rate of IVF is, at best, about 55%. Researchers seeking to improve the success of IVF need to observe the interaction between sperm and eggs in order to better understand the factors that favour fertilization. Obviously, larger sperm and eggs would be easier to observe, even with the aid of microscopy. On this basis, which of the following vertebrate groups might be a good model for studying IVF because they are likely contain species with large sperm and eggs? Group of answer choices a) fish b) amphibians c) reptiles d) birds e) mammals
Internal fertilizationa. can prevent the drying out of gametes and zygotes.b. must take place on land.c. is practiced by humans.d. requires that males have a penis.e. Both a and c are correct.
