What is crossbreeding?

• A. Selecting the best individuals within the same breed
• B. Mating different breeds
• C. Breeding for uniform appearance
• D. Crossing animals of different species

Answer: (B)

Crossbreeding means mating animals from different breeds to combine desirable traits from both lines. By bringing together distinct genetic backgrounds, you can often gain hybrid vigor and improve overall performance, such as growth, fertility, or adaptability. The description that fits best is mating different breeds, because it directly involves two or more breeds within the same species. Choosing individuals within the same breed is about improving that single breed through selection, not combining different breeds. Breeding for a uniform appearance aims for consistency within a population, which is typical of purebreeding or linebreeding rather than crossbreeding. Crossing animals of different species would be interspecific hybridization, which is not the same as crossbreeding between breeds.
