Question

Study the characteristics of a population represented in the graphs below.
Which type of selection this population is likely to undergo?

• A. Directional selection
• B. Stabilising selection
• C. Disruptive selection
• D. Balancing selection

Answer 1

The correct option is A Directional selection

This population is likely to undergo directional selection, in which the population changes towards one particular direction. Here, directional selection is favoring small sized individuals and more individuals of that type will be present in next generation. Hence, the mean size of population changes.

So, the correct answer is 'Directional selection'.
