Asexual reproduction is a mode of reproduction by which offspring arise from a single organism, and inherit the genes of that parent only. There are various asexual reproduction methods by which the unicellular organisms divide, as follows:
- Fission is that type of asexual reproduction in which the parental body divides into daughter cells simultaneously during the unfavorable conditions.
- Budding is a type of asexual reproduction by which offsprings arise from a single organism.
- Vegetative propagation is a form of asexual reproduction of a plant where only one plant is involved and the offspring is the result of one parent.
