Explanation:
Given:
Average weight gain between weeks 2 and 4 = 10 grams
The narrow-sense heritability of the weight gain between 2 and 4 weeks
= 25%
Then
Average weight gain would be expected among the offspring of parents whose average gain was 15 grams-
by the formula:
Average weight gain between weeks + (h) (Average weight gain between weeks - parents average gain )
= 10 + 0.25 (15-10)
= 10 + 0.25 (5)
= 10 + 1.25
= 11.25
Thus, the correct answer is - 11.25
