  1. Bell work • Does cloning increase diversity? • Genetically modified organisms: • 1) Are always harmful • 2) Are always micro-organisms • 3) May be beneficial • 4) Arise naturally

  2. Genetic engineering CONTINUED…

  3. Selective Breeding • Artificially selecting & breeding only organisms w/ a desired trait to produce the next generation • 2 types: Inbreeding & Hybridizations • Domesticated animals • Crop plants

  4. Selective breeding • Decide which characteristicsyou desire • Choose parents that show these characteristics • Select the best offspring from parents to breed the next generation • Repeat :)

  5. Examples!!! Disease-resistant wheat Dairy cows MORE MILK! BIGGER COWS!

  6. Inbreeding • Crossing individuals who are closely related • The wanted gene will become more & more prevalent in the offspring • The recessive gene defects show up more frequently

  7. Hybridization • Choosing & breeding organisms that show strong expression for 2 different traits to produce offspring that express both traits.
