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 tails of peacocks 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 red color of a male cardinal is there to attract the female cardinal.

If the female cardinals device another means to selecting their mates, then the male cardinals shall have no use of the red shade.

Therefore variations in the red shade shall decrease due to disuse.

The male cardinals shall adapt to the new method of selection.

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

Explanation:

Natural selection may be defined as the differential reproduction and survival of the individual due to their differences in the phenotype. Natural selection acts as the main driving force for evolution.

The male cardinal red color gets change or may show variation as it is no longer used by them to attract the females. The red shade variation get decreases and may get changed over time. The red color trait is non advantageous and get extinct with time.

Thus, the correct answer is option (3).

humans, along with other animals and plants, have linear chromosomes that are arranged in pairs within the nucleus of the cell. the only human cells that do not contain pairs of chromosomes are reproductive cells, or gametes, which carry just one copy of each chromosome.

answer; i believe the correct answer is ( proteins );
