Asexual reproduction is a method of reproducing without the need of a second parent. Essentially, one parent creates an exact duplicate of itself, meaning the offspring has only that parent's genes. This differs from sexual reproduction, in which male and female gametes (sex cells) fuse together to form a new individual that has genes from each parent.
Plants and some single-celled or lower-level organisms reproduce asexually. Animals also can reproduce in this manner, but despite the examples we were just looking at, we're talking about mostly simple organisms. Humans, for example, can't reproduce asexually. So don't think you can just create a copy of yourself; it won't work.
Asexual reproduction can be advantageous for organisms that don't have others of their type around. Without many mates, an organism might not be able to reproduce. And if it can't reproduce, it can't pass on its DNA and traits.
Asexual reproduction also can allow animals to colonize and take over an environment quickly and efficiently. Because asexual reproduction results in an exact copy of the parent, the best genes for the environment will successfully takeover and thrive.
Types of Asexual Reproduction
There are four main forms of asexual reproduction in animals: budding, fission, fragmentation, and parthenogenesis. Each form is similar in that one organism is able to create many more organisms without the need for a mate, but they differ in the mechanism by which they create those organisms.
