asexual and sexual reproduction in animals

• asexual reproduction - No need of two parent. Ensuring that offspring carries same genetic information as their parent.
• Binary fission - asexual reproduction by a separation of the body into two new bodies. it is a process of asexual reproduction used by prokaryotes. Animals are multicellular, eukaryotic organisms and do not use binary fission. Some animals are able to reproduce asexually with a process called fission, which is analogous, but not the same as binary fission.
• Fragmentation - breaking of body parts into fragments, followed by regeneration, and regrowth of lost parts. Ex: starfish
• Budding is an asexual reproduction method in which a new organism develops from a bud of an existing organism. Until the new organism matures, it remains attached to the parent organism
• Sexual reproduction - involves male and female parents. It’s a combination of the genes from both parents.
• Gametogenesis - is the process of forming male and female gametes with a haploid number of chromosomes (n) from diploid cells (2n) of the cells present in the gonads of the organisms.
• Spermatogenesis

  is the production of sperm from the primordial germ cells.
• spermatogenesis is the process by which haploid spermatozoa develop from diploid cells in the seminiferous tubules of the testis.
• Oogenesis is the process of formation of female gametes

  the produced female gamete is known as an ovum.
