The greatest advantage of animal breeding compared to other disciplines is that...

• A. It happens instantly
• B. The change is temporary and reversible
• C. The change is cumulative, permanent, and long-term
• D. It is unpredictable

Answer: (C)

Genetic improvement in animal breeding comes from selecting and mating individuals with superior breeding values, so the favorable alleles become more common in every new generation. Because these are heritable changes, the average performance of the population shifts in a lasting way and continues to improve over generations. Each generation adds to the gain, making the improvement cumulative, permanent, and long-term.

This isn’t instant—the benefits require time across generations to accumulate. It isn’t temporary or reversible, since the changes are stored in the gene pool. And with proper design—accurate breeding value estimates, strong selection, and reasonable generation intervals—these gains can be predicted and planned, not left to chance.
