parthenogenesis.

2006-06-25 05:21:01 · answer #1 · answered by ATP-Man 7 · 0 0

Asexual reproduction. refers to reproduction without gender. There is also parthenogenesis which permits a population of all females to reproduce without males by what is essentially a natural cloning process. Additionally some species are capable of having some members change gender in a single sex environment and then reproducing normally in the new gender. Some species are also different genders at different times in their lives, ie male as a juvenile and female as an adult. Also their are species with fully functional hermaphrodites, that is individuals which can function as both genders.
Finally, in addition to reproduction without sex, single celled organisms also have sex without reproduction. That is they exchange genetic information with other members of their own species and can change portions of their DNA.

asexual reproduction......like plants and bacteria, there are no male or female, they can reproduce themselves, thus producting and exact DNA copy of itself.

Here is the reference from Wikipedia.....
Asexual reproduction (also known as agamogenesis) is a form of reproduction which does not involve meiosis, gamete formation, or fertilization. In laymen's terms, there is only one "parent" involved. This form of reproduction is common among simple organisms such as amoeba and other single-celled organisms, although most plants produce asexually as well (see vegetative reproduction).

Because it does not require male and female participation, asexual reproduction occurs faster than sexual reproduction and requires less energy. Additionally, asexual reproduction produces an exact replica of the parent due to the lack of genetic recombination. From an evolutionary standpoint, one could thus argue that asexual reproduction is inferior because it stifles the potential for change. However, there is also a significantly reduced chance of mutation or other complications that can result from the mixing of genes.

Many, but not all, single-celled organisms produce asexually through binary fission. Some single-celled organisms rely on one or more host organisms in order to reproduce, but most literally divide into two organisms. An exception to the rule are ciliates, which reproduce both sexually and asexually. All prokaryotes (the vast majority of which are unicellular) reproduce asexually. [citation needed]

There are three types of asexual reproduction utilized by plants: regeneration, vegetative reproduction, and spore formation. The last type, spore formation, involves the production of reproductive cells called spores that contain DNA and develop into a new organism after dispersal. This method of reproduction is found in the ferns, and involves sporogenesis without meiosis. Thus the chromosome number of the spore cell is the same as that of the parent producing the spores.

There are 2 terms that come to mind:

1. Asexual reproduction is when an individual produces offspring that are genetically identical to itself. The offspring are produced by mitosis (cell division).

2. Parthenogenesis is the ability of an unfertilized egg to develop and hatch.

Both do not require both a male and female present. Hope this helps. Need more info, please let me know. :)

Asexual reproduction?

2006-06-20 12:09:46 · answer #5 · answered by Joey 5 · 0 0

In addition to asexual reproduction (aka budding) there is a fascinating process called parthenogenesis, in which a gender monoculture (only one gender is present, such as all males) induces some creatures to CHANGE GENDER, allowing sexual reproduction! Now THAT is a stunt!

Asexual reproduction, myosis.

It is asexual reproduction, as practically everyone else has stated. Uni-cellular organisms generally use that practice. Budding, as far as I know, is applied more towards organisms that can produce more of themselves by having pieces of themselves chopped off (The starfish is an excellent example of this). But, I have been known to be wrong.

Asexual reproduction would be reproduction with oneself. This is common in bacteria. Although bacteria can do what is known as conjugation to exchange genetic material before they split.

asexual reproduction is a type of reproduction where an organism replicates itself, by budding or dividing, without the involvement of other organisms.

Asexual. The prefix "a" means without.
