An example of natural selection is the red color of a male cardinal. the females of the species choose mates based on the vibrant colors of the males' feathers. if females begin using different criteria than feather color when they choose mates, what would most likely happen to the color of the male cardinals over time? increased variation in the shades of red because the selection pressure has been relieved increased variation in the shades of red because the cardinals try different ways to impress the females decreased variation in the shades of red because no form of the trait is advantageous decreased variation in the shades of red because the only reason for variation was selection pressure

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

Explanation:

The last option also seems correct, but selections is somehow aleatory. You cannot consider "reason" as a factor.

The correcta answer is opcion B). "decreased variation in the shades of red because no form of the trait is advantageous".

Explanation:

If females choose males for other traits than the red color of feathers, it is probably that the feathers would decrease the variation in the shades of red because no form of the trait is advantageous.

On the one hand, females do not choose males for this characteristic anymore, which means that this color is not advantaging for mating. On the competition with other males, they will have to develop the other trait that makes them look better genetically.

On the other hand, these bright colors make males very visible to predators, a pressure that will make the turn to less bright visible colors for better hiding and fewer chances to get caught.

the cell cycle is the final answer! : )
