Reproductive Systems in Various Vertebrates
Pre-lab questions
1. What is the function of a reproductive system?
2. Why is a reproductive system essential to evolution?
3. What do you think is similar about the reproductive system of fish, amphibians, birds, reptiles, and
mammals?
4. What do you think is different about the reproductive system of fish, amphibians, birds, reptiles,
and mammals?
Procedure
1. Your group will research the reproductive system of a particular class of vertebrates.
2. Use the following pages in the green IS textbook as well as the Internet to complete your research.
3. *Class Osteichthyes (Bony Fish): p.494
*Class Reptilia (Reptiles) p.518
*Class Amphibia (Amphibians) p. 502
*Class Aves (Birds) p.528
*Class Mammalia (Mammals) p. 542-543
4. Then your group will create a poster in order to teach the class about your class of vertebrate
5. As each group presents, you will take notes on each system. If you need more info for your project,
you can read the pages too!

Analysis Questions
1. Draw an example of an amniotic egg and include the function of amnion, chorion, yolk sac,
embryo, and allantois in the analysis section
2. How are the reproductive systems similar in fish, amphibians, birds, reptiles, and mammals?
3. How are the reproductive systems different in fish, amphibians, birds, reptiles, and mammals?
4. Describe the selective pressures that would have led to the differences fish, amphibians, birds,
reptiles, and mammals.
