Crossbreeding is defined as which of the following?

• A. The process of breeding with animals of the same breed.
• B. The practice of improving a single trait within a breed.
• C. Mating animals of different breeds.
• D. Keeping a population within a single line.

Answer: (C)

Crossbreeding means mating animals from different breeds to blend the strengths of each lineage. This approach aims to combine desirable traits from distinct breeds and often yields hybrid vigor, where offspring show improved performance over either parent. It’s different from breeding within the same breed, which focuses on trait improvement without introducing new breed genetics. Selecting for a single trait within a breed is a form of within-breed improvement that doesn’t involve crossing breeds, and keeping a population within a single line describes linebreeding or inbreeding, which concentrates genetics rather than mixing breeds.
