Term for Product of Realized Heritability and Selection Differential
The product of realized heritability and selection differential is known as:
- Response to selection — Correct Answer
- Limit of selection
- Intensity of selection
- Accuracy of selection
Explanation:
Correct Answer: Response to selection
Response to selection (R) = h² × S, where h² is realized heritability and S is the selection differential.
Factors Affecting Response to Selection (R)
- Intensity of selection (i)
- Additive genetic variance (σA)
- Accuracy of selection (rAP)
- Population size
- Generation interval
Realized heritability = R / S. This is distinguished from heritability in narrow sense (h²N = VA/VP), which is a population parameter, while realized h² is computed from actual selection response.
