1 Review Give and example of selective breeding Review what is the relationship between genetic variations and mutations.Explanation Write a paragraph in which you suggest ways that plants could be genetically altered to improve the world’s food supply
3 Selective BreedingMethod of breeding where the organisms that breed are picked due to certain traitsPeople have done this for a long time with many speciesNative Americans selectively bred teosinte to produce corn.
4 HybridizationCrossing dissimilar individuals to bring together the best of both organismsIndividuals produced by such crosses are often hardier than either of the parentsCan increase the disease resistance or increase food production.
5 InbreedingContinued breeding of individuals with similar characteristicsUseful in preserving certain traits- dog breedsIncreases the chance that a cross between two individuals will bring together two recessive alleles for a genetic defect.
6 BiotechnologyApplication of a technological process, invention, or method to living organisms.
