A male cardinal's red color is an example of a trait affected by natural selection. The females of the

based on the vibrant colors of the males' feathers. If females begin using different criteria than feat

mates, what would most likely happen to the color of the male cardinals over time?

increased variation in the shades of red because there is no advantage in one specific color

increased variation in the shades of red because the cardinals try different ways to impress the

decreased variation in the shades of red over time because no form of the trait is advantageous

decreased variation in the shades of red after a single generation

The answer is: decreased variation in the shades of red over time because no form of the trait is advantageous.

Explanation:

"Natural Selection" is a process that allows an organism to adjust/adapt to its environment. This is also related to their ability to survive, as well as their ability to produce an offspring.

The male cardinals' bright red color allows it to attract the female cardinals. This is the reason why the male's color is red, while the female's color tend to be dull or less reddish. This is affected by the process of natural selection. Males tend to increase the shade variation of red in order to have more off springs.

If the females will begin to use a different criteria in choosing their mate, then the trait of male cardinal's having red color will decreased in its variation over time. This is because, the trait will have no more advantage to him, so he doesn't need the trait to be passed on to the future generation.
