Answer:

The correct answer is - 11.25

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
