The ways in which variant genotypes could be increased in the environment or individuals with a particular trait may increase in population are:
  • through natural selection (of variations brought during the course of time)
  • by genetic drift (accidental changes in the frequency of some genes in a population)
  • by mutation
  • by sudden decrease or increase in the availability of food during a period of some generations.
