The correct answer is Line breeding. Line breeding is an inbreeding program whereby an individual is mated to its descendants. The mating of animals of wider degrees of a relationship than those selected for close breeding is called line breeding. It promotes uniformity in the characters. Line breeding is the breeding program that is needed if the farmer wants to keep the relationship of the next generation with a particular ancestor at a high level. It can be used when the breed is in its infancy to develop the breed or to can also be used in an established breed or strain when an outstanding animal is discovered.
