How are phenotypes and genotypes related to natural selection?
Natural selection favours phenotypes that bestow a reproductive advantage, thereby increasing the frequency of alleles (genotype) producing those phenotypes.
What happens to the variation in traits which are under strong natural selection?
It depends on which form is being favored by selection. In directional selection, one of the extremes of the "bell curve" has the advantage. In this case selection will "drive" the variation toward one end. Example: a population of birds where long, narrow beaks have an advantage; variation will be pushed toward longer, narrower beaks until that stops being advantageous. On the other hand, sometimes selection favors the "middle of the road" form. In this case, the variation will be driven toward the middle and the extremes will drop away. For example, a population of moths where a medium shade of coloring has the advantage (not too light or too dark); in this case, you'll get more gray moths, less black and white. This is "stabilizing selection".
What is the definition of natral selection?
The process whereby individuals more suited to a particular environment or food source tend to pass on their advantage to descendants.
Can RNA undergo natural selection and evolve?
Yes, RNA can undergo natural selection and evolve. RNA molecules can replicate and mutate, leading to variations in their sequences. Those variations that confer a selective advantage, such as improved stability or catalytic activity, are more likely to be passed on to subsequent generations. This process of selection and evolution is known as RNA evolution.
Which process do heterozygous organisms use to release energy?
natural selection
How is the seniority an unfair advantage in the selection of committees?

How could this be an advantage to the insects how could this trait have evolved through natural selection?

Will natural selection act on tongue rolling in a human population?
No because theres no selective advantage
Does the World Cup winner has any advantage on the selection proccess of the FIFA World footballer of the year?
The advantage they have is the winner needs not qualify for the next world cup.
How has artificial selection been used to shape the looks and behavior of farm animals such as the cow and family pets such as the domesticated dog?
Humans select certain traits from a dog or cow's offspring to use for whatever purpose they have in mind. These traits are then passed on down to future offspring and selected further by other humans who purchase and use the animals for their use. Thus that's what "artificial selection" is all about: humans doing the genetic selection and looking for certain qualities in domesticated animals that they can "exploit" or use to their advantage.
How are phenotypes and genotypes related to natural selection?
Natural selection favours phenotypes that bestow a reproductive advantage, thereby increasing the frequency of alleles (genotype) producing those phenotypes.
How recruitment and selection process maintain a sustained competitive advantage?
Recruitment and selection is the process of outfitting an organization with the right people. When the human resource department focuses on attracting and retaining people who have the skills necessary to carry out the strategic objectives of the organization, then the organization will have a competitive advantage over their competition.
