Which statement is a valid claim that could be made using the data in the graph?
Directional selection is occurring because the graph favors an extreme.
Stabilizing selection is occurring because the average is favored.
Disruptive selection is occurring because the two extremes are favored.
Biodiversity selection is occurring because of the greater variation.

Low or very high weight are two extremes.

If these two extremes do not survive then only those between these extremes will survive.

We therefore conclude that those babies with an average weight will survive.

The average weight will depend on the two extreme weights.

From the given explanations the correct answer is :

Stabilizing selection is occurring because the average is favored.

The weight of the new-born baby is considered as a major factor for his/ her survival.

Over-weight and underweight can reduce the chances of survival of a baby.

It is a very rare case and is occurred approximately 1.5 % new-born across the world.

This condition gets prevalent if the mother gives the birth of more than one baby at a time.

In these cases, the flow of blood through the blood vessels of the baby gets affected. Hence chances of survival are reduced.
