• Binary fission is a type of asexual reproduction.
  • It occurs when a parent cell splits into two identical daughter cells.
  • This can result in very rapid population growth.
  • Under ideal conditions, bacterial populations can double every 20 minutes.
  • Lack of genetic variation increases the risk of extinction.
  • Without variety, there may be no organisms that can survive a major change in the environment.
  • Prokaryotes have a different way to increase genetic variation.
  • This is called genetic transfer or bacterial conjugation.
  • Genetic transfer makes bacteria very useful in biotechnology.
