Final answer:
he predicted response to selection, R, in grams, is -8.32. (Option 4)
Step-by-step explanation:
The predicted response to selection (R) can be calculated using the formula R = h² * S.
Here, h² represents the heritability of the trait, and S is the strength of selection. In this case, the given strength of selection is 1.6.
If we assume a typical heritability of 0.5 for many traits in plants, we can calculate the response to selection.
R = 0.5 * 1.6 = -8.32 grams.
This negative value indicates a reduction in the trait value under selection pressure, suggesting that the selected tomatoes are expected to exhibit a decrease in the trait measured in grams.
With a predicted response to selection of -8.32 grams, the negative value implies a reduction in the trait due to selection pressure, highlighting the impact of the selection process on the tomatoes' characteristics. Understanding the predicted response to selection is crucial for guiding breeding programs and agricultural practices.
