<p>Animal reproduction is necessary for the survival of a species. In the animal kingdom, there are innumerable ways that <a data-lesson="summarizing-community-ecology" data-subject="biology" data-tutorial="population-community-ecology" href="https://app.ulearngo.com/biology/population-community-ecology/summarizing-community-ecology">species</a> reproduce. Asexual reproduction produces genetically identical organisms (clones), whereas in sexual reproduction, the genetic material of two individuals combines to produce <a data-lesson="reproduction-methods" data-subject="biology" data-tutorial="reproductive-system" href="https://app.ulearngo.com/biology/reproductive-system/reproduction-methods">offspring</a> that are genetically different from their parents.</p>
<p>During <a data-lesson="animal-sexual-reproduction" data-subject="biology" data-tutorial="reproductive-system" href="https://app.ulearngo.com/biology/reproductive-system/animal-sexual-reproduction">sexual reproduction</a> the male gamete (sperm) may be placed inside the female’s body for internal fertilization, or the sperm and eggs may be released into the environment for external fertilization. Seahorses, like the one shown in the figure above, provide an example of the latter. Following a mating dance, the female lays eggs in the male seahorse’s abdominal brood pouch where they are fertilized. The eggs hatch and the offspring develop in the pouch for several weeks.</p>

Introduction to Animal Reproduction

Biology studies life and living organisms. Biology can be divided into different sections that cover the morphology, physiology, anatomy, behavior, and so on of living organisms.

Biology

Explore the fascinating and complex process of animal reproduction, including asexual and sexual reproduction, sex determination, hormonal control, human reproductive anatomy and pregnancy, fertilization and early embryonic development, organogenesis and vertebrate axis formation.
