Potatoes b. Bananas c. Apples d. Cereal grains When people domesticate plants, we a. harvest them from wild populations. b. alter them genetically to meet our needs. c. tame them d. plant them in greenhouses. The primary goals of plant-breeding programs are a. improved yield. b. disease resistance c. stress tolerance. d. pest resistance. e. all of the above. is the only major crop that was domesticated in the present US. c. Squash d. Sunflower a. Tobacco b. Corn e. Rice Plant breeding is a. accelerated evolution guided by humans who are practicing artificial selection b. picking out the best products of natural selection c. intended to increase genetic diversity of plants in populations d. a field that just started with the development of moleculargenetics e. None of the above The development of agriculture started at least years ago. a. 1 million b. 100,000 c. 10,000 d. 1000 Development of homozygous purebred strains is brought about by a. cross-pollinating individuals of the same species orvariety. b. artificially inducing the doubling of chromosome numbers. c. repeated inbreeding. d. crossing heterozygous varieties with one another. e. All of these answers are correct. The main advantage of sexual reproduction over asexual reproduction is that sexual reproduction a. results in the production of genetically identical individuals. b. requires a greater expenditure of energy c. results in greater genetic variability among the offspring. d. usually results in a greater number of offspring.
