Answer:
In the cardinals, if the females start using a different criterion than the color of the feather when they choose couple, most likely to happen is that decreased variation in the shades of red because no form of the trait is advantageous.
Explanation:
Options for this question are:
- <em>Increased variation in the shades of red because the selection pressure has been relieved.</em>
- <em>Increased variation in the shades of red because the cardinals try different ways to impress the females.</em>
- <em>Decreased variation in the shades of red because no form of the trait is advantageous.</em>
- <em>Decreased variation in the shades of red because the only reason for variation was selection pressure.</em>
In the context of natural selection, male cardinals court females using the coloring of their feathers as a form of sexual selection. This means that the shades of red in the feathers are a selection criterion in these birds, and the more visible shades represent an advantage.
But, if the selection criterion was not the color of the feathers, this trait would no longer represent an advantage in the competition between the males to be chosen as a mate. Instead, the trait that would determine sexual selection would be the one that experiences an increase in its variation<em>.</em>

The statement is true. DNA replication process happen during the cell cycle.
Since the
speed of many physiological processes in marine organisms is determined by the
temperature, the first consequence of the changes in the conditions of the
medium becomes offset the timing of seasonal events, such as the timing of
spawning fish. There have also offset migration routes and spawning areas. So,
as a result of warming in the Sea of Japan, spawning navaga shifted to an
earlier date, because of the reduction of the area of "cold spots"
in the eastern Bering Sea shelf feeding migration of pollock, halibut and crab
are lengthened, but because of the temperature rise to the east of Japan,
spawning saury expanding. These changes significantly affect the success of
reproduction, resulting in changes populations of their fishery.
Answer:
Genetic variation is a term used to describe the variation in the DNA sequence in each of our genomes. ... Individuals of a species have similar characteristics but they are rarely identical, the difference between them is called variation
