Correct answer: D. All the above
- A. Dominance variance
- B. Additive x dominance epistasis
- C. Dominance x dominance epistasis
- D. All the above
Explanation
Specific combining ability reflects non-additive gene action, especially dominance variance and epistatic interactions such as additive × dominance and dominance × dominance effects. Therefore, all listed components may contribute.
