A farmer has found several strawberries in his field that are sweeter and larger in size than the rest of the field. How Could this farmer reproduce strawberry plants similar to those he has found in this field?

The correct answer is 3.5 grams

Explanation:

In the given question, there is a need to use the equation R = h² × S. Here, R is the response to selection, it is the difference between the mean of the initiating population and the mean of the progeny of the selected parents. In the given question R = 5g - 2g = 3g.  

S is the selection differential, it is the difference between the mean of the initiating population and the mean of the selected parents. In the given case, S = 6g - 2g = 4g

Substituting the values of R and S in the given equation, we get:  

3g = h² (4g)

h² = 0.75

If the selected plants' average weight is 4 grams, then S would be 2 grams, and R = 0.75 × 2 = 1.5g

The predicted average weight of strawberries from the progeny plants would be 2g + 1.5g = 3.5 g.  

that is wrong, its not thymus.
