Q:

Which animals reproduce asexually?

A:

Quick Answer

Although sexual reproduction is a more common method of reproduction among animals, a few species, such as starfish and sea anemones, produce offspring via asexual reproduction. Asexual reproduction, in contrast to sexual reproduction, does not require the mating of two parents to produce an offspring. This means that there is no fusion of gametes and, in turn, no exchange of genetic information from parents to the offspring.

Full Answer

Since asexual reproduction does not involve the exchange of genetic information, the offspring produced from this method of reproduction are essentially clones of their parents. Offspring, in addition to being genetically identical to their parents, are identical to one another as well. Asexual reproduction is more commonly found in plants, and may take place in several ways. Most plants that perform asexual reproduction have within their bodies male and female organelles. Similarly, a few animal species have this characteristic too. In starfish, reproduction takes place primarily through fission, which involves the division of the central disc into two equal halves. After dividing, the two halves have the unique ability to regenerate all the requisite missing parts to form a new and complete starfish. Less commonly, starfish reproduce via autonomy, which involves the shedding of their arms. The arms eventually develop new discs; eventually, the seven remaining arms grow to form a new starfish.

    What animals live in the Indian Ocean?

    A:

    The Indian Ocean, like many of Earth's oceans, serves as home to a diverse number of species, including anenomefish, Great White sharks, bottlenose dolphins, blue whales, sea turtles, jellyfish, stingrays, sea anemones, sea snakes, worms and stonefish. Creatures inhabiting the Indian Ocean range in size from tiny microorganisms to some of the largest animals on the planet, such as large sharks and blue whales. Some creatures pose little threat to humans and other mammals, while others contain lethal venom or emit potent toxins, potentially causing harm.

    What are the characteristics of animals?

    A:

    The main characteristics of animals are sexual reproduction, eukaryotic cells, movement, multicellularity and heterotrophy. Animal cells are differentiated and organized into tissues, except in sponges. Animal tissues serve specific functions, and they include muscle tissue, nervous tissue, connective tissue and epithelial tissue.

    How do animals reproduce?

    A:

    The State University of New York states that animals reproduce by several sexual and asexual methods, with sexual reproduction, defined as the production of gametes with half of each parent's DNA and their union into diploid organisms, predominating. Sexual reproduction can be done externally, with eggs and sperm united outside an organism, or internally. Asexual reproduction takes a large number of forms, which vary between taxonomic groups.

    How is selective breeding carried out?

    A:

    Selective breeding, also called artificial selection, is carried out by mating animals or crossing plants with desired characteristics or traits to produce offspring in which those traits are more dominant, according to Encyclopedia Britannica. The breeder attempts to isolate the genes responsible for the desired trait in subsequent generations so the quality becomes more pronounced and fixed.
