Date: March 20th, 2017- Happy Spring!! Aim # 60: How have organisms benefited from reproductive technologies? HW: Daily Review of class notes. Test Corrections due Tuesday (Must get signed!!) Castle Learning due Thursday Test on Human Reproduction Friday Do Now: Where does the embryo implant and develop in the female reproductive system? What does a developing embryo need? What waste products are produced? What is the function of the placenta? What is the function of the umbilical cord? What trimester is the most dangerous? Why?

Aim #60: How have organisms benefited from reproductive technology?

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

2) 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.

3) Applications of Reproductive Technology: Medical Applications: In-Vitro Fertilization Artificial Insemination Cloning?? Amniocentesis & Karyotyping

a) In-Vitro Fertilization Sperm fertilizes egg in a test tube The embryo is then Implanted into a mother’s uterus.

b) Artificial Insemination Inserting sperm inside females fallopian tube

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

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

d) Amniocentesis & Karyotyping Amniotic fluid is withdrawn from a woman's uterus to test for certain problems in the fetus, such as genetic defects.

4) Sonograms - Ultrasound Use of sound and echo to create an image of the developing embryo

Applications of Reproductive Technology: Agriculture: 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. Using artificial insemination, scientists can generate hundreds of offspring from one farm animal. 3) Selective Breeding

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

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.

Summary What is reproductive technology? What is infertility? What is in-vitro fertilization? What is artificial insemination? Why would someone get an amniocentesis? How do we produce an image of the developing fetus? What is selective breeding? What is the example that we spoke about in class today?
