Detailed explanation-1: -Selective breeding involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics. Humans have selectively bred plants and animals for thousands of years including: crop plants with better yields.

Detailed explanation-2: -Selective breeding is a process to develop new organisms with desirable characteristics.

Detailed explanation-3: -Since the time man first domesticated animals, selective breeding has been used to develop better or more useful strains (or breeds) of the animals from the genetic diversity that naturally exists in the population of a single species.

Detailed explanation-4: -Farmers and breeders allowed only the plants and animals with desirable characteristics to reproduce, causing the evolution of farm stock. This process is called artificial selection because people (instead of nature) select which organisms get to reproduce.

Detailed explanation-5: -The correct answer: The true statement about selective breeding and genetically modified organisms is (a) Farmers have been able to produce new varieties of crops by selective breeding alone.
