Multiple fission is a type of asexual reproduction in single-celled organisms where a single parent cell divides into multiple daughter cells, each of which will develop into a new individual.

This type of reproduction occurs in some protozoans, such as Amoeba, and is a quick and efficient way of producing offspring. Multiple fission is common in environments where there is a scarcity of resources, as it enables a single organism to multiply quickly and increase its chances of survival.

The characteristics of multiple fission include:

  • A rapid increase in population.
  • Genetic uniformity among offspring.
  • Ability to adapt to changing environments.
