Directional selection is shown on a graph as selection against an extreme. This occurs when individuals at one extreme of a trait distribution have lower fitness than individuals with intermediate phenotypes or those at the opposite extreme. Over time, this can lead to a shift in the average phenotype of a population.
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.
Mitotic spindle fibers are microtubule structures that form during cell division to help separate duplicated chromosomes into two daughter cells. They aid in the precise distribution of genetic material by attaching to and moving chromosomes to opposite ends of the cell.
The opposite of huge Is tiny.
Opposite leaves are opposite each other, on opposite sides of the plant stem. Alternate leaves are on opposite sides of the stem but they are higher or lower than each other - not opposite
When natural selection favors the intermediate version of a characteristic, it is referred to as stabilizing selection. It is the opposite of disruptive selection.
One pattern of natural selection polygenic traits is directional selection, in which one end of the spectrum leads to increased fitness and the other end decreased fitness. Disruptive selection is when both ends of the spectrum lead to increased fitness and the middle leads to decreased fitness and it leads to two distinct phenotypes being selected for. It's opposite is stabilizing selection, in which the middle has the best fitness and the two extremes have decreased fitness.

Natural selection changes the genetic makeup of a population by favoring some genotypes over others. It does so through the differential reproduction of those genotypes. Put simply, if I possess a variant of a trait (and the genotype underlying it) which allows me to leave behind more adult offspring than those with different variants of that trait, then my variant will become more common in the population than the others. The result is a change in the frequency of the gene variants: mine increases in frequency at the expense of the others. This change in the frequency of gene variants (known as alleles) over time in a population is the basic definition of evolution itself.
Making a product widely available..... Opposite to selective distribution.....associated with market penetration
Directional selection tends to eliminate individuals at one extreme of a trait spectrum, favoring those at the opposite extreme. Over time, this can lead to a shift in the average value of the trait within a population.
No: the opposite.
The opposite of majority rule is minority rule. This means that the population or selection that is least represented will decide the outcome.
No, the exact opposite is true.
Add to allows you to select area which will be added to selection (already selected area) and subtract is opposite: allows you to subtract portion from already selected area.
go to layer(menu bar)-new-layer via copy , this will create new layer with selection which can be edited,if its wrong selection(opposite of what you want) delete layer(right click-delete) go back and invert selection :select(from menu)-inverse, and again layer-new-layer via copy
Selective breeding or Artifical Selection is a theory by Charles Darwin that he included in his first book "Origin Of Species" its the opposite of the Natural Selection which states that the strongest specie will survive. The artificial selection or Selective Breeding states the human and scientific interaction to produce a new specie by modifying genetics and DNA.
