The change in trait with time as a result of natural selection is shown above. This type of natural selection is _____.

The body weight of adult female of a strain of Drosophila is 1.8±0.45 mg (mean ± standard deviation). In a laboratory experiment, each of the three groups (A, B, C) of this stain was subjected to a different type of selection pressure having influence on female body weight. After many generations of experimental selection pressure, the body weight changed as follows:

Group A: Body weight distribution – normal, 1.8 ± 0.08 mg

Group B: Body weight distribution – Bimodal at 1.4 and 2.2 mg

Group C: Body weight distribution – Normal, 2.2 ± 0.08 mg
