Overview

Asexual reproduction is reproduction without sex. In this form of reproduction, a single organism or cell makes a copy of itself. The genes of the original and its copy will be the same, except for rare mutations. They are clones. The main process of asexual reproduction is mitosis. This type of reproduction is common among some single-cell organisms, for example, amoeba. Many plants also reproduce asexually.

Types of Asexual Reproduction

Binary fission: A cell splitting and becoming two cells (overview)Some organisms like bacteria reproduce using binary fission. They split in two, so one bacterium becomes two bacteria. This always leads to daughter cells, and the offspring will be identical to the parent. Budding: Budding is similar to binary fission, but it is used by plants and some animals, which cannot simply split in half as bacteria can. It is when a small part of a plant or animal breaks off and then, while they are separated from their "mother", they start to grow until both the "parent" and the "offspring" are the same size and both are capable of budding again. This may happen many more times. Spores: Fungi (for example, mushrooms) produce spores, which may be asexual or sexual. The asexual spores have the genetic material inside, which allows them to make a whole new organism identical to its parent.
