Question

The curve on the left shows the height of a population of penguins . the curve on the right shows the population five years later. What has happened to this population

Answer 1

The type of natural selection demonstrate is B. stabilizing selection.
There are different types of natural selections, each affecting the population density of a specific allele in a different way. In stabilizing selection, the non-extreme trait is maximized. This is seen in the curve as there is less population observed at the extreme ends of the spectrum but a greater population lying in the average, less extreme zone.
