Detailed explanation-1: -Linebreeding is a type of inbreeding. It involves breeding together more distant relatives, such as cousins.
Detailed explanation-2: -Inbreeding is of two types: close inbreeding and line inbreeding. Close inbreeding involves mating between first-degree relatives and even between second-degree relatives. Linebreeding involves the mating of animals that are not so closely related but have at least one common ancestor in the pedigree.
Detailed explanation-3: -In animal breeding, techniques such as inbreeding, linebreeding, and outcrossing are utilized. In plant breeding, similar methods are used. Charles Darwin discussed how selective breeding had been successful in producing change over time in his 1859 book, On the Origin of Species.
Detailed explanation-4: -Intensive inbreeding – Mating of closely related animals for several generations. Linebreeding – A mild form of inbreeding that maintains a high genetic relationship to an outstanding ancestor.
