Asexual Reproduction


General Information1. Benefits of asexual reproduction include: no need for finding a mate (there is only one parent, i.e. yeast), rapid populating(able to reproduce many times exponentially i.e. sporulating mushrooms can send off thousands of spores at once), and quick(don't have to carry them for months, and then take care of offspring i.e. bacteria split immediately).Drawbacks of asexual reproduction include: no genetic variation (offspring is clone of parent i.e. bacteria's genetic makeup),susceptible to extinction (no genetic variaton means the same weaknesses).

Asexual ReproductionMedha Rao 5th

This form of asexual reproduction happens in bacteria. Here, the cell splits into two, including it's DNA. However, it does not go through the process of mitosis to do so. Since bacteria don't contain the same type of chromosomes as higher organisms such as plants and animals, they go through the process of binary fission.

2. One drawback of asexual reproduction is that there is no genetic diversity. Each offspring is a clone of it's parent. While this is great when wanting to get strong genes, it can also be the complete opposite. However, in sexual reproduction, since there are two parents giving their DNA, there is more chance of genetic variation. For example, bacteria reproduce asexually, and each offspring is genetically identical to it's parent. Each bacteria looks the same, with the exception of mutations. If you look at human offspring, you will see many different characteristics. Some are tall, short, brown-eyed, blue-eyed, dark skinned, light skinned, etc. This difference in characteristics between offspring is due to sexual reproduction.

Budding is another form of asexual reproduction. For example, in a Hydra, cell division will happen at one particular spot, and that will lead to a bud to form at that location. This outgrowth will eventually separate or remain attached to form colonies.



Sporulation is a form of asexual reproduction that involves producing spores(a specialized cell enclosed in a protective case) which are released from the parent. When environmental conditions are favorable, the released spores will develop into a mature organism. This way of reproducing can be found in some mushrooms, moss and molds.

Fragmentation happens when a part of an organism breaks off and grows into a mature organism. This can commonly be seen in mushrooms and mold. In this case, with the mushroom, the hyphae break off from the mushroom, and seek nutrients and water. This helps them eventually grow into a mushroom.
