How many Types of Asexual Reproduction?

Define Splitting/Binary Fission, Budding, Vegetative Propagation and Runners.

There are several methods of asexual reproduction. They all produce genetic copies of the parent organism.

Splitting:

Most unicellular protists and bacteria reproduce simply by splitting into two cells. Some bacteria can divide into two new organisms every 10-20 minutes.

Budding:

During budding, a small part of the parent's body grows into a tiny and complete version of the parent. Some organisms, such as cnidarians, sponges, and some fungi, can reproduce through budding. 

Other Forms of Asexual Reproduction in Animals:

Some species of fish, insects, frogs, and lizards go through asexual reproduction in a different way. The females of these animals produce eggs.

Normally these eggs would be fertilized by male sex cells, but in some cases, fertilization never takes place. The eggs just develop into a new animal without fertilization.

For example, when queen honeybees lay eggs, some are fertilized and others are not. The fertilized eggs develop into females, or worker bees. The unfertilized eggs become males, or drone bees.

Vegetative Propagation:

Plants can undergo a form of asexual reproduction.

Vegetative propagation is asexual reproduction in plants that produces new plants from leaves, roots, or stems.

Runners:

Runners are plant stems that lie on or under the ground and sprout up as new plants.

Strawberry plants, aspen trees, ferns, and most grasses can reproduce using runners.
