Question

What population is most likely experiencing disruptive natural selection?

-pumas with medium brown fur are more successful than light or dark pumas
-predators can easily see very light or very dark lizards in a population
-medium colored peppered moths are more likely to be eaten by birds
-red butterflies are more likely to survive than blue butterflies

Answer 1

• Medium colored peppered moths are likely to be eaten by the birds.

Step-by-step explanation:

When the nature selects the two peripheral traits rather than selecting the mean character value , it is called disruptive selection . Here the medium colored moths would be eaten by the birds , so ultimately the light and the dark colored moths will increase in number.

If we plot a graph, then two peaks are formed and there is a depression in the centre of the graph.

There are two other types of Natural selection

Stabalizing selection:-

• When the nature selects the mean character value, then it is called stabalizing selection.
• The peak gets higher and narrower in the middle of the graph.

Directional selection:-

• When the nature selects any one of the peripheral character value then it is called directional selection.
• The peak shifts to one direction in the graph.
