In a population of birds, brightly colored males and very dull males survive best. Which type of selection is this, and what is most likely true about the proportion of males of intermediate coloring?(1 point)

Question

Responses

Directional; males of intermediate coloring make up a small part of the population.
Directional; males of intermediate coloring make up a small part of the population.

Disruptive; males of intermediate coloring make up a small part of the population.
Disruptive; males of intermediate coloring make up a small part of the population.

Stabilizing; males of intermediate coloring make up the greatest part of the population.
Stabilizing; males of intermediate coloring make up the greatest part of the population.

Directional; males of intermediate coloring make up the greatest part of the population.

Answer 1

The scenario describes a situation where both brightly colored males and very dull males have higher survival rates compared to males with intermediate coloring. This indicates that there are two extremes being favored, while the average or intermediate phenotype is being selected against.

This is an example of disruptive selection. In disruptive selection, two extreme traits are favored and the intermediate phenotype is selected against.

Given this information, the correct response would be:

Disruptive; males of intermediate coloring make up a small part of the population.
