Neutral selection is the changes in a gene pool of a species that are a result of random neutral occurrences that do not give any advantage to that species. Neutral selection does not depend upon adaptation, fitness, or natural selection.
If you are referring to the 'Nearly Neutral' theory of natural selection, then read on. If this is a typo for 'Natural Selection', skim down to the next paragraph. The 'Nearly Neutral' theory of evolution states that for a change to come about in the population as a whole, the new characteristic must be better than or equally good as the old characteristic for the change to occur. If, for example, a population of dog has brown eyes, and a new, mutant, blue-eyed dog arrives, then this is not going to be a worse characteristic than brown eyes. This means that the concentration of the blue-eyes in the population can go on a 'random walk' and may become the norm.
Natural selection is the main idea behind evolution. Basically, it is based on several observations:
1 - Some members of the species are different from other members of the species
2 - Parents look like their children
3 - Some characteristics will help survival
With these in mind, it is clear that those who are better equipped will tend to survive more and pass on their characteristics to their children. That's Natural Selection.

What is one factor that affects natural selection and artificial selection?
Variation in the organisms under selection. In both artificial selection and natural selection there must be heritable variations that have the possibility of being in the case of artificial selection what the selector wants in the organism and in thje case of natural selection survivability and reproductive advantages.
The mode of natural selection in which both extremes in the range of a phenotype are favored is termed?
That would be disruptive selection.
What is the difference between choice and selection?
A choice is what you make from an available selection. A selection defines available choices.
What are 4 factor Darwin's used for his theory of evolution?
Artificial Selection, Sexual Selection and Natural Selection.
What selection favors organisms with phenotypes that are at one extreme rlative to the average phenotype?
Tends to result in a population whose individuals have extreme traits is what? ----> it is directional selection
What is the tone of the selection?
The tone of the selection is informative and neutral.
Which mutations are NOT subject to natural selection - lethal physiological neutral or morphological?
Neutral mutations confer no benefits or handicaps and are therefore not affected by natural selection.
Why the advers selection problem plays no role if both parties are risk neutral?
The simple answer is that both adverse selection and moral hazzard impose risk to the party. When this party is risk neutral, he or she would not be adversly affected by the risks associated with the transactions including risk of adverse selection.
Can a 1995 Honda Passport 4X4 be flat towed?
remove both front and rear driveshafts or if your 4x4 shifter has a neutral position put the transfer case in neutral and transmission in neutral and it should be fine if no neutral is presant in the 4x4 selection remove drive shafts.
What is the best gear to drive on the highway for a 2001 Chevy Malibu?
the top gear, which will include overdrive. It will be the first selection after neutral.
Which kind of selection eliminates extreme phenotypes?
disruptive selection
