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: -As the name implies, selective breeding is a deliberate process of breeding selected animals or plants for specific genetic qualities. Inbreeding and hybridization involve the artificial selection and crossing of animal or plant species, both with different results.
Detailed explanation-3: -Crossbreeding and inbreeding are mating extremes along a continuum: inbreeding is the mating of animals that are more closely related than the average in a population, and crossbreeding is the mating of animals that are less related than the average in a population.
Detailed explanation-4: -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.
