b) Out-crossing
c) Cross-breeding
d) Inbreeding

Answer 1

a) Out-breeding: Out-breeding is the breeding of the unrelated animals, which may be between individuals of the same breed (but having no common ancestors), or between different breeds (cross-breeding) or different species (inter-specific hybridisation). [1]

b) Out-crossing: This is the practice of mating of animals within the same breed, but having no common ancestors on either side of their pedigree up to 4-6 generations. [1]

c) Cross-breeding: : In this method, superior males of one breed are mated with superior females of another breed which allows the desirable qualities of two different breeds to be combined. [1]

d) Inbreeding: Inbreeding refers to the mating of more
closely related individuals within the same breed for 4-
6 generations. [1]
