Detailed explanation-1: -Inbreeding. If we want to establish a population of organisms with predictable characteristics we tend to “inbreed”. Inbreeding is when the animals bred are very close relatives, such as siblings. Continued inbreeding results in offspring that are very genetically alike.
Detailed explanation-2: -Hybridization may also be used to transfer other desirable characteristics from one group or species to another, to combine valuable traits from two species into a single group, and to produce sterile individuals.
Detailed explanation-3: -Inbreeding breeding of organism that genetically similar to maintain desired traits. Dogs breeds are kept pure this way. Its how a Doberman remains a Doberman.
Detailed explanation-4: -The meats sold today are the result of the selective breeding of chickens, cattle, sheep, and pigs. Many fruits and vegetables have been improved or even created through artificial selection. For example, broccoli, cauliflower, and cabbage were all derived from the wild mustard plant through selective breeding.
