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But, if the selection criterion was not the color of the feathers, this trait would no longer represent an advantage in the competition between the males to be chosen as a mate.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>
Its that food dropped on the ground is safe to eat and will not be covered in germs as long as its picked up within 5 seconds after its dropped.
What happens to the population density and competition if the birth rate decreases?
The birth rate would increase is the population density competition increased.

Answer: True
Explanation:
The statement on Codominance is TRUE, while the one on incomplete dominance is also TRYE. So, the whole statement is TRUE.
In codominance, both phenotypes are expressed in homozygotes OR heterozygotes; but in incomplete dominance, the heterozygous exhibit a phenotype that is intermediate OR different from the two homozygotes.
So, TRUE is the answer
