Flowers b/c gametes produced in structures of flowers sperm in anthers of flower, egg in carpel of flower. Prevent fertilization by cutting off anthers pollen to fertilize these flowers came from diff plant. Called cross-pollination or a cross: true breeding plants chosen- when self-fertilized passed traits without change from one gen to the next. Studied 7 characters one was flower colour some had purple, others white.
