Examples of asexuality in the following topics:
-
- Fungi reproduce sexually and/or asexually.
- Perfect fungi reproduce both sexually and asexually, while imperfect fungi reproduce only asexually (by mitosis).
- Fungi reproduce asexually by fragmentation, budding, or producing spores.
- The most common mode of asexual reproduction is through the formation of asexual spores, which are produced by one parent only (through mitosis) and are genetically identical to that parent .
- There are many types of asexual spores.
-
- Animal reproduction is essential to the survival of a species; it can occur through either asexual or sexual means.
- The known methods of reproduction are broadly grouped into two main types: sexual and asexual.
- The division of a bacterial cell into two daughter cells is an example of asexual reproduction.
- Organisms that reproduce through asexual reproduction tend to grow in number exponentially.
- Many organisms can reproduce sexually as well as asexually.
-
- Plants have developed various strategies, both sexual and asexual, to ensure reproductive success.
- Some plants reproduce sexually while others reproduce asexually, in contrast to animal species, which rely almost exclusively on sexual reproduction.
- Plant sexual reproduction usually depends on pollinating agents, while asexual reproduction is independent of these agents.
- Vegetative reproduction is a type of asexual reproduction.
-
- Plants can reproduce asexually, without the fertilization of gametes, by either vegetative reproduction or apomixis.
- Many plants are able to propagate themselves using asexual reproduction.
- Plants have two main types of asexual reproduction: vegetative reproduction and apomixis.
- An advantage of asexual reproduction is that the resulting plant will reach maturity faster.
- Different types of stems allow for asexual reproduction.
-
- Phylum Deuteromycota is a polyphyletic group of asexually-reproducing fungi that do not display a sexual phase; they are known as imperfect.
- Reproduction of Deuteromycota is strictly asexual, occuring mainly by production of asexual conidiospores .
-
- Therefore, there is an obvious benefit to an organism that can produce offspring whenever circumstances are favorable by asexual budding, fragmentation, or asexual eggs.
- These methods of asexual reproduction do not require another organism of the opposite sex.
- In addition, in asexual populations, every individual is capable of reproduction.
- In theory, an asexual population could grow twice as fast.
- The only source of variation in asexual organisms is mutation.
-
- Zygomycota, a small group in the fungi kingdom, can reproduce asexually or sexually, in a process called conjugation.
- The fungi usually reproduce asexually by producing sporangiospores .
- Zygomycetes have asexual and sexual life cycles.
-
- Also, protozoal piroplasms are sporozoan parasites, and so they possess both sexual and asexual phases.
- These parasites, within the red blood cells, form a distinctive structure called a "Maltese Cross" that is composed of four attached merozoites undergoing asexual budding.
- This asexual process results in hemolytic anemia.
- The sporozoites enter the erythrocytes and undergo asexual reproduction as previously mentioned.
- Babesia is capable of undergoing both sexual and asexual reproduction in its life cycle.
-
- This fact distinguishes animals from fungi, protists, and bacteria where asexual reproduction is common or exclusive.
- However, a few groups, such as cnidarians, flatworms, and roundworms, undergo asexual reproduction, although nearly all of those animals also have a sexual phase to their life cycle.
- Some animal species (including sea stars and sea anemones, as well as some insects, reptiles, and fish) are capable of asexual reproduction.
- In contrast, a form of asexual reproduction found in certain insects and vertebrates is called parthenogenesis where unfertilized eggs can develop into new offspring.
- However, for animals that are limited in their capacity to attract mates, asexual reproduction can ensure genetic propagation.
-
- Plants can undergo natural methods of asexual reproduction, performed by the plant itself, or artificial methods, aided by humans.
- Natural methods of asexual reproduction include strategies that plants have developed to self-propagate.
- Artificial methods of asexual reproduction are frequently employed to give rise to new, and sometimes novel, plants.
- Grafting is an artificial method of asexual reproduction used to produce plants combining favorable stem characteristics with favorable root characteristics.
- Distinguish between natural and artificial methods of asexual reproduction in plants
