उत्तर

If the selection favours small or large-sized individuals, more individuals of that type will be present in the next generation. With continued selection over generation mean size of the population would have changed it. It is directional selection which brings about evolution in the population. In the natural selection, both small size and long sized individuals, natural selection would be disruptive type. It produces two peaks in the distribution of traits that may lead to the development of two different population.
