Largely for show purposes, but also for guidance in gardening, certain species and named cultivars have been determined by the ADS to be miniatures and must compete by themselves in daffodil shows. This means that new plants are created without seeds or spores. Figure 24.2. The sexual phase is called gametogony and the asexual phase is called sporogony. Do chickens asexually reproduce? - food05.com daffodils generally do not reproduce from seeds. The examples of the organism that reproduce by binary fission include: Parthenogenesis is the type of asexual reproduction in which a female organism gives rise to offspring without mating with a male partner.

Artificial propagation involves the development of new plants inside a laboratory. If you contribute half of your genes and your partner contributes half of his or her genes, the genetic makeup of the new individual is far more diverse than if you were to produce a genetically identical offspring through asexual reproduction.
