Answer:
3.5 g
Explanation:
To solve this particular question, we will use the equation
R = h² * S, where
R, is the response to selection. This response to selection is the difference between the mean of the starting population and the mean of the progeny of the selected parents.
S, the selection differential, is the difference between the mean of the starting population and the mean of the selected parents
From the above explanation, we then have.
R = 5 g - 2 g = 3 g.
S = 6 g - 2 g = 4 g.
On Substituting the values into the equation, we have
3 g = h² * (4 g)
3 g = 4gh²
h² = 3g/4g
h² = 0.75.
If the selected plants are said to average 4 g, this then mean that S would be 2 g. If S is 2 g, using the earlier stated formula,
R = 0.75(2 g) = 1.5 g.
Therefore, the predicted average weight of strawberries from the progeny plants would have to be
2 g + 1.5 g = 3.5 g.
