• A. Only A

• D. Only B

Answer 1

The correct option is C A and B

Selective mating of animals to produce offspring with desired qualities is called animal breeding.

It is of two types: inbreeding and out-breeding.

Inbreeding involves the mating of closely related individuals (having common ancestors) within the same breed for 4- 6 generations.

Out-breeding involves mating of unrelated animals.

It is of three types

• Out-crossing: Mating of animals within the same breed that do not have common ancestors on either side of their pedigree up to 4-6 generations is called out-crossing.
• Cross-breeding: In cross-breeding, superior males and females of two different breeds are mated. The progeny obtained is called crossbreed and usually has desirable traits of both the parents.
• Interspecific hybridisation: It is the practice of mating male and female animals of two different but closely related species.

Hence, option c is correct.
