Populations have a genetic variation among individuals and that is important to the populations ability to survive in different situations that have an affect on the natural selection. There are different factors which can increase or decrease the genetic diversity, and influencing natural selection. These factors can include an environmental factor, one of the major factors, which can cause changes in the genetic variation of a population and influence the natural selection. A famous and important example of the environmental factors affecting natural selection was made during the industrial revolution when many more gray moths made up the moth population. This was so that they could blend in with the soot from factories to avoid predators.
Natural selection is an evolutionary process in which the population of the organisms or species adapt and change. Mutation, migration, and certain environmental factors affect natural selection.
Natural selection is defined as the ability of the organism to adapt to its environment to survive and reproduce more. Natural selection can decrease genetic diversity and lead to directional selection.
However, genetic variation is vital for organisms to survive in various situations. Certain factors can increase or decrease genetic diversity, for example, during the industrial revolution, the gray moth population increased. It was due to the camouflaging of the gray moths to the gray smoke or soot released from the factories.
Therefore, the population of gray moth were better suited to the environment and tend to survive and reproduce during natural selection.
