The correct Answer is:
To determine the root of any breeding program, we need to analyze the options provided and understand the fundamental concepts behind breeding. ### Step-by-Step Solution: 1. **Understanding Breeding Programs**: Breeding programs are designed to produce new varieties of plants or animals that possess desirable traits. These traits may include higher yield, disease resistance, or improved quality. **Hint**: Consider what breeding aims to achieve in terms of traits. 2. **Evaluating the Options**: - **(a) Mutation**: This refers to random changes in the genetic material. While mutations can introduce new traits, they are not the foundational basis for breeding programs. **Hint**: Think about whether mutations are a controlled or random process in breeding. - **(b) Green Revolution**: This term refers to a period of agricultural transformation aimed at increasing food production through new technologies and high-yield varieties. It is a result of breeding efforts rather than the root of breeding itself. **Hint**: Is the Green Revolution a cause or an effect in the context of breeding? - **(c) Genetic Variability**: This is the variation in genetic makeup among individuals within a species. Genetic variability is crucial for breeding programs as it provides the raw material for selection and crossing to create new varieties. **Hint**: Consider why variability is important for creating new traits in breeding. - **(d) Genetic Similarity**: This would imply that the organisms are genetically alike, which would limit the potential for creating new varieties. Breeding relies on differences, not similarities. **Hint**: Would similarity help in producing diverse traits? 3. **Conclusion**: After evaluating all options, the most fundamental aspect of any breeding program is **genetic variability**. It allows breeders to select and cross individuals to create new varieties with desired traits. ### Final Answer: (c) Genetic variability
