The term breeding refers to the mating and production of offspring by animals or other living organisms. It can also refer to the activity of controlling or mediating in the mating and reproduction of organisms. Breeding is also used synonymously with the term reproduction, which is the biological process where new individual organisms—referred to as offspring—are produced from parent organisms. Reproduction is a fundamental and important feature of all known life in the planet, with each individual organism existing as a result of this biological process. There are two types of reproduction: sexual and asexual.
Sexual reproduction often requires two individuals or gametes to be involved in the process. However, asexual reproduction can be more complicated. An individual organism with the capability to reproduce asexually is able to reproduce without the involvement of another individual of the same species. A bacterial has the ability to divide itself into two daughter cells. But asexual reproduction is not limited to single-celled organisms.
For many animals, breeding season is the most suitable season for reproduction. Typically, a breeding season has favorable conditions, as well as abundant food and water, which makes it ideal for wild animals and even birds to procreate. Species that have a breeding season have evolved—through natural means—to have sexual intercourse with other individuals of the same species during a particular time of the year in order to achieve the best chances of reproductive success.
Some species also breed in colonies (or large communities), and this practice is known as communal breeding. With these species, it is common to see large groups of individuals gathering in a particular location.
This section contains scientific information on breeding, a term that refers to the mating and production of offspring by animals or other living organisms.
