Asexual reproduction includes fission, budding, fragmentation, and parthenogenesis, while sexual reproduction is achieved through the combination of reproductive cells from two individuals.
The ability of a species to reproduce through fragmentation depends on the size of part that breaks off, while in binary fission, an individual splits off and forms two individuals of the same size.
Budding may lead to the production of a completely new adult that forms away from the original body or may remain attached to the original body.
Observed in invertebrates and some vertebrates, parthenogenesis produce offspring that may be either haploid or diploid.
Sexual reproduction, the production of an offspring with a new combination of genes, may also involve hermaphroditism in which an organism can self-fertilize or mate with another individual of the same species.
Key Terms
binary fission: the process whereby a cell divides asexually to produce two daughter cells
hermaphroditism: having sexual organs of both sexes
parthenogenesis: a form of asexual reproduction where growth and development of embryos occur without fertilization
