Final answer:

Mating of animals of the same breed but having no common ancestors on either side for 4-6 generations - (iv) Outcrossing

c. Interspecific hybridization:

Interspecific hybridization refers to the mating of organisms from different but related species to produce hybrid offspring with desirable traits. The offspring produced are sterile, e.g, the mule is a sterile hybrid produced by interspecific hybridisation between horse and donkey.

c. Mating of animals of two different species -(ii) Interspecific hybridization

d. Crossbreeding:

Crossbreeding refers to the mating of individuals of two different breeds. The superior male of one breed is mated with the superior female of the other breed to produce hybrid offspring with desirable traits, e.g, Hisardale is a breed developed in Punjab by crossing Bikaneri ewes with Marino rams.
