2. Aim: How have organisms benefited from reproductive technology?

3. What is Reproductive Technology? 1.Methods that assist organisms to produce offspring. 2.Methods that aid in the examination of developing offspring.

4. Why might some people need reproductive technologies? Some people cannot become pregnant because of problems with their hormones, ovaries, testes, or other parts of their Reproductive systems. Infertility – cannot produce offspring.

5. Applications of Reproductive Technology: Medical Applications: 1)In-Vitro Fertilization 2)Artificial Insemination 3)Cloning?? 4)Amniocentesis & Karyotyping

6. In-Vitro Fertilization Sperm fertilizes egg in a test tube

7. The embryo is then…. Implanted into a mother’s uterus.

9. Artificial Insemination Inserting sperm inside females fallopian tube

10. How do we store sperm, eggs & embryos for in-vitro fertilization? Frozen in a bank

11. Cloning Take nucleus from individual who will be cloned & insert it into an anucleated egg Why Clone?

12. Amniocentesis & Karyotyping Amniotic fluid is withdrawn from a woman's uterus to test for certain problems in the fetus, such as genetic defects Down’s Syndrome).

13. Sonograms - Ultrasound Use of sound and echo to create an image of the developing embryo

14. Applications of Reproductive Technology: Agriculture: 1)Scientists have genetically modified plants using DNA Recombinant Technology to be resistant to disease. These modified plants can then be cloned to produce thousands of genetically identical offspring. 2)Using artificial insemination, scientists can generate hundreds of offspring from one farm animal. 3) Selective Breeding

15. Selective Breeding Meaty cow Milk producing cow To obtain organisms with desired traits

16. Applications of Reproductive Technology: Ecology: Embryos from endangered species have been transplanted into related species, who later give birth to offspring that are no different than they would be if they developed in the bodies of the endangered species themselves.
