Selection is called a negative source because it acts by removing individuals with unfavorable traits from the population. This process reduces the frequency of those traits in subsequent generations, effectively "negating" their presence. Negative selection helps to eliminate harmful traits and promote survival of individuals with beneficial traits.

No, natural selection works on that genetic variation presented to it.
A selection of multiple cells is oftenreferredto as a range.
This is called Artificial Selection. Artificial Selection is the source of most modern produce and meat. For instance, corn is has been artificially selected to have larger kernels and cobs to provide more food. One theorized origin of Corn is a small grass bush called teosinte. Artificial selection is not entirely beneficial however. Certain Dog Breeds subjected to generations of artificial selection have developed propensities for painful and deadly illnesses. Heart, muscular, respiratory, and neurological dysfunctions number among the problems some breeds experience. Charles Darwin studied artificial selection by breeding traits in pigeons.
Some individual organisms are better equipped to live and reproduce in their environment than others. If what makes them better equipped is heritable, their offspring will be more numerous and will tend to inherit the same traits or qualities themselves. The opposite will happen to those poorly equipped. They will have fewer or no offspring, and their negative traits will tend to disappear from the population as time goes on. These two tendencies are called positive (natural) selection and negative (natural) selection respectively. Natural selection is always relative to the environment. What is advantageous in one environment may not be so in another, and what is disadvantageous (deleterious) in one environment may not be so in another.
Selection is called a negative process in Business as more candidates who apply for employment are rejected than employed. That is why Selection is called a negative process.
Immunology relies on both negative selection and positive selection. Negative selection, or non resultant, provides for discounting a method of treatment. Positive selection, or improvement can at times be found by elimination through negative selection.

The final decision on which offeror will be selected
Negative selection and positive selection are two processes that occur in the immune system to ensure the proper functioning of immune cells. Negative selection eliminates self-reactive immune cells that could potentially attack the body's own tissues, while positive selection promotes the survival and maturation of immune cells that can effectively recognize and respond to foreign pathogens. In essence, negative selection removes harmful immune cells, while positive selection enhances the development of beneficial immune cells.

The source selection process is typically overseen by a Source Selection Authority (SSA), who is responsible for evaluating proposals and determining which one offers the best value to the government or organization. The SSA evaluates factors such as technical merit, cost, and past performance in accordance with the established evaluation criteria. Ultimately, the SSA makes the final decision on the selection of the source based on this comprehensive assessment.

The term Adverse Selection is also known as Anti-Selection and Negative Selection. Adverse Selection is a term referring to a market process when undesired results happen when buyers and sellers have access to different information.
