Shook Me All Night Long!

Human reproduction begins with sexual intercourse, followed by nine months of pregnancy before childbirth. Many years of parental care is required before a human child becomes independent.Individual organisms come and go, but, to a certain extent, organisms transcend time through producing offspring. Reproduction in animals occurs in two primary ways: through sexual reproduction and through asexual reproduction.In asexual reproduction, one individual produces offspring that are genetically identical to itself. These offspring are produced by mitosis. There are many invertebrates, including sea stars and sea anemones for example, that produce by asexual reproduction. Common forms of asexual reproduction include:

Budding

In this form of asexual reproduction, an offspring grows out of the body of the parent.

Gemmules (Internal Buds)

In this form of asexual reproduction, a parent releases a specialized mass of cells that can develop into offspring

Sponges exhibit this type of reproduction.

Fragmentation

In this type of reproduction, the body of the parent breaks into distinct pieces, each of which can produce an offspring.


Planarians exhibit this type of reproduction.
Regeneration

In regeneration, if a piece of a parent is detached, it can grow and develop into a completely new individual.

Echinoderms exhibit this type of reproduction.
Parthenogenesis

This type of reproduction involves the development of an egg that has not been fertilized into an individual.


Animals like most kinds of wasps, bees, and ants that have no sex chromosomes reproduce by this process. Some reptiles and fish are also capable of reproducing in this manner.
