Answer 1

The correct option is A A – F, B – F, C – F, D - T

Selective mating of animals followed by their selection to obtain superior genotypes with desired qualities is called animal breeding.

Inbreeding and out-breeding are types of animal breeding.

In inbreeding, very closely related individuals within the same breed are mated.

Out-breeding is the mating of unrelated animals that either belong to the same breed, or different breed and even different species. The animals share no common ancestors, at least for 4 - 6 generations.

Out-breeding is of three types: Out-crossing, Cross-breeding, Interspecific hybridisation.

Out-crossing is the mating of animals within the same breed (but having no common ancestors on either side of their pedigree up to 4-6 generations). The offspring of such a cross is called an out-cross. It is the best breeding method for animals that are below average in productivity (milk production) and growth rate (meat production).
