animal reproductive system, any of the organ systems by which animals reproduce. The role of reproduction is to provide for the continued existence of a species; it is the process by which living organisms duplicate themselves.
Reproduction may be asexual when one individual produces genetically identical offspring, or sexual when the genetic material from two individuals is combined to produce genetically diverse offspring. Asexual reproduction in animals occurs through fission, budding, fragmentation, and parthenogenesis.
Reproduction, process by which organisms replicate themselves. Reproduction is one of the most important concepts in biology: it means making a copy, a likeness, and thereby providing for the continued existence of species. Learn more about the process of reproduction in this article.
Reproduction is the process of producing individuals of the same kind. Most organisms reproduce by mating, which increases the genetic variability of the organism. The males and females have separate reproductive organs known as gonads.
Asexual reproduction occurs in prokaryotic microorganisms (bacteria and archaea) and in many eukaryotic, single-celled and multi-celled organisms. There are several ways that animals reproduce asexually, the details of which vary among individual species.
What Is Reproduction? All organisms reproduce, including plants and animals. The biological process involves an organism producing and/or giving birth to another organism. Just because all organisms reproduce doesn’t mean the methods of reproduction are the same, however.
What you’ll learn to do: Discuss methods and features of animal reproduction. Most animals are diploid organisms, meaning that their body (somatic) cells are diploid and haploid reproductive (gamete) cells are produced through meiosis.
Reproduction is the process by which organisms create new life. There are two main types: asexual and sexual reproduction. Asexual reproduction involves one parent, producing offspring identical to the parent. Sexual reproduction involves two parents, resulting in genetically unique offspring.
The role of reproduction is to provide for the continued existence of a species; it is the process by which living organisms replicate themselves. Unlike most other organ systems, the reproductive systems of higher animals have not generally become more complex than those of lower forms.
Some organisms can reproduce by themselves (called asexual reproduction), while others need both an egg and sperm to make offspring (sexual reproduction). In sexual reproduction, small sperm from a male must fuse with the often-larger egg from a female.
