Selective Breeding. Student Learning Objectives. One/Many Idea:. Define selective breeding. Describe Inbreeding. Describe Hybridisation. Describe Polyploidy . Which of these is/are not genetically manipulated?. describe and explain how sheep breeders can achieve genetic progress in their flocks. . A sheep farmer can improve production by good management of the feeding, health and reproduction of a flock. Careful breeding improves a flock over a long time, because good production traits are selected for and passed on to the young over many generations. . 7.00. Critique agriculture animals.
