Question

Define asexual reproduction. Describe two methods of asexual reproduction in animals.

Answer 1

Hint: The type of the reproduction that is not involve in the change in the number of chromosomes and fusion gametes is a type of asexual reproduction. The oppsprings generate from a multicellular organism and a single cell inherit the genes of the parents in the asexual reproduction. For example: - Binary Fission. Lack of diversity found in the asexual reproduction because of the offspring’s susceptible to the same disease.

Complete answer:
 In the binary asexual reproduction, production of the simplest form, and parent cells divided into the two new daughter cells that’s grow smaller to normal size and process occurred inside the bacteria and protozoa. On the budding reproduction system cells of the parents divide into two unequal parts and develop the buds, a process occurring inside the yeast and hydra. In the third case of spore reproduction only single cells released from the parent and germinate to form a new individual, and obtained spores have hard outer covering and some have flagella present on it.
In the asexual reproduction without fertilization and meiosis one parent organism produce the offspring that inherit all the DNA from the one parent, most of the time genetically identical. This kind of results seen in the mold on bread. Mold is a kind of fungus that can reproduce by asexual and sexual reproduction, not only fungus but also plants, animals, protists and bacteria can produce asexually.

Note: During the cell division new cells generate two identical cells in the asexual reproduction, in the bacteria such as a unicellular fungi and protists. But in human with the parthenogenesis obtained the artificial asexual reproduction but note occurred naturally in the human body. And a gamogenesis, fission, vegetative reproduction, budding, spore formation and fragmentation is the seven type of asexual reproduction.
