Differentiate out- crossing, cross breeding and interspecific hybridisation.

Explanation

Out crossing : It is the mating of the animals of the same breed but which have no common ancestors on either side of the pedigree up to 4-6 generations.
Cross - breeding : It is the mating of superior males of one breed with superior females of another breed ( both with desirable characters).
Inter-specific hybridization : It is the mating of male and females of two different but related species.
