In a population of tomato plants mean fruit weight is 60 g and narrow-sense heritability (or realized heritability - h2) is 0.3.

Predict the results of artificial selection (the mean weight of the progeny) if tomato plants whose fruit averaged 80 g were selected from the original population and interbred.

Answer:

The mean weight of the progeny is 66 grams

Explanation:

Given -

Mean fruit weight of tomato plant (M1) = 60 g

Narrow sense heritability (h2) = 0.3 g

Mean weight of tomato plant selected for artificial selection (M0) = 80 g

h_2 = \frac{M_2 - M_1}{M_0 - M_1}

Substituting the given values in above equation, we get -

0.3 = \frac{M_2 - 60}{80 -60} \\0.3 = \frac{M_2 -60}{20} \\6 = M_2 -60\\M_2 = 6 + 60\\M_2 = 66

The mean weight of the progeny is 66 grams

No. Scientists have never predicted a earthquake. We do not know how, and we do not expect to know how any time in the foreseeable future.
