Natural Selection and Artificial Selection Text Reference: pg. 305-311 Homework: pg. 311 #1-3, 5-7, 11, 12 Natural Selection: Selective Pressure: Example of Selective Pressure Fitness: What does a high degree of fitness mean? ________________ or ________________are a type of biotechnology. _________________ is the use of technology and organisms to produce useful products. Artificial selection has had a large impact on human survival as most of the food we eat—grains, fruits, vegetables, meat, and milk—comes from species that have been selectively bred. For example, artificial selection has resulted in cows that produce more milk, chickens that grow rapidly and have large muscles, rice, corn, wheat, and vegetables are bred to increase nutritional value and harvest yield to be drought-resistant or pest-resistant. Crop breeders now understand that selective breeding must be balanced to maintain genetic variation within the crops and the ability of the plants to respond to conditions of environmental change.
