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
Genetic engineering CONTINUED…
Selective Breeding • Artificially selecting & breeding only organisms w/ a desired trait to produce the next generation • 2 types: Inbreeding & Hybridizations • Domesticated animals • Crop plants
Selective breeding • Decide which characteristicsyou desire • Choose parents that show these characteristics • Select the best offspring from parents to breed the next generation • Repeat :)
Examples!!! Disease-resistant wheat Dairy cows MORE MILK! BIGGER COWS!
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
Hybridization • Choosing & breeding organisms that show strong expression for 2 different traits to produce offspring that express both traits.
