1. Selective Breeding Selective Breeding: allowing only those organisms with desired characteristics to reproduce. –How could you use selective breeding to develop dogs with more intelligence? –Selective breeding takes advantage of natural genetic variation (the trait must already exist in the population)

2. 2 Methods of selective breeding 1.Hybridization: crossing dissimilar individuals together to get the best of both organisms Ex: Killer Bees – While attempting to create a bee that produces more honey in tropical climates scientist bred a European honey bee with a African honey bee. 2.Inbreeding: the continued breeding of individuals with similar characteristic Ex: Purebred Dog Breeds – dog breeds are created by breeding individuals with similar characteristics to ensure that the combination of traits will be passed on to the next generation. Selective Breeding

3. In order for selective breeding to work, you need a wide variation of genetic traits. –Explain why you cannot use selective breeding to create a monkey that glows in the dark? How do new traits get introduced into a population? –Induce mutations to develop new traits in a population (Mutations are the ultimate source of new genetic traits)
