Which breeding strategy is specifically designed to exploit both breed complementarity and hybrid vigour?
Correct answer: A. Crossbreeding
- A. Crossbreeding
- B. Close breeding
- C. Pure breeding
- D. Random mating
Explanation
Crossbreeding combines desirable characteristics from different breeds and can produce heterosis in the crossbred progeny. Pure breeding and close breeding do not specifically combine different breed gene pools for this purpose.
