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But, if the selection criterion was not the color of the feathers, this trait would no longer represent an advantage in the competition between the males to be chosen as a mate.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>
Answer:
I believe the first one would be incomplete dominance, the second would be multiple alleles, and the third would be codominance.
Explanation:
The first one would be incomplete dominance because the child has a blend of the man's straight hair and the woman's curly hair, but neither of two hair types are completely dominant (if that makes sense).
The second one would be multiple alleles because, well, there are multiple alleles listed (more straightforward than the other two).
And the third one would be codominance because the traits of red color and white color are equally dominant.
Answer: Water cannot/is slower to be gradually soaked into it's soil in built environments with large unregulated soils, but rushes the environment, transporting toxins and ecological sewage into our rivers, killing fish, animals and possibly even us.
The correct answer that would best complete the given statement above would be the term ADAPTIVE RADIATION. African cichlids are a group of closely related fish species. There are at least 500 known species living in three small lakes. Over time, specialized teeth and body colorations have evolved for each species in response to mutations and competition for food and mates. This change over time is an example of ADAPTIVE RADIATION. Adaptive radiation by definition, is <span>the diversification of a group of organisms into forms filling different ecological niches.</span>
