  2. Extra limbs What’s wrong with our frogs? • Extensive internal problems • Missing or extra legs • Unusual bone and cartilage formations in spine and lower jaw

  3. Extra leg What’s wrong with our frogs? • Eye deformities • Reproductive deformities that result in sterility • Distended bladders due to nonfunctional digestive systems

  4. What we wanted to find out... • Are the increasing number of frog birth defects a sign of the thinning of the ozone layer? • Specifically, can we duplicate these deformities by using an ultraviolet light to simulate over-exposure to the sun?

  5. The test subjects...

  6. Xenopus Mating • Xenopi are sexually mature at 10 months to 1 year • Usually mate during a genetically programmed time of year • Human Chorionic Gonadotrophin treatments can be used to induce breeding at any time

  19. Bred eggs Purchased eggs The control groups...

  20. Looking back... • We did not get opportunity to see the effects of UV radiation of embryonic frogs • We still learned from the experience • Biological materials are unpredictable • Redundancy and experimental flexibility are the key to success
