Alternation of generations (A.o.G.) is an evolutionary process in which one organism gives rise to another. It is common to observe such processes in plants and animals, including ferns. This is because each organism contains both haploid and diploid organisms. The multicellular organisms give birth to new organisms, and this process continues for as long as the original entity exists. There is also an example of an A.o.G. that occurs in bacteria.
Changing generations is an important aspect of life in plants, and it is also evident in animal populations. In some animals, the alternation of generations occurs between male and female gametophytes. The gametophytes in flowering plants produce both sexes. The gametophytes produce the flowers. In some species, there are both male and female sporophytes. In some species, the sporophytes give rise to only one type of flower.
The theory of alternation of generations has various applications in biology. In plants, it occurs for many reasons. For example, the onset of the reproductive phase in the first generation is accompanied by the development of the second and third generation. In some instances, this may occur as a result of the development of different genes. In the latter case, two-thirds of an organism will have the same characteristics. The process is also known as asexual reproduction.
The alternation of generations occurs in virtually all types of multicellular algae, including seaweeds and freshwater forms. Although most of the organisms that undergo alternation of generations are homomorphic and free-living, some red algae species have a more complex triphasic alternation of generations, where the sporophytes produce gametes before development of the young. This phenomenon is called asexual reproduction, and the cycle repeats itself over again.
During the vegetative growth cycle, two separate organisms emerge: sporophyte and gamete. Both of these are genetically separate. If the sporophyte produces more than one child /outcome, it will be able to reproduce in the same manner as the other. If the sporophyte produces a male, it will produce a female. The process of sexual reproduction is not identical in all organisms, though.
An example of an alternation of generations is observed in the spores of plants. The haploid gametophyte produces gametes, while the diploid sporophyte produces a female. The alternation of generations also occurs in many types of fungi. These organisms produce seeds through mitosis and are considered to be heterogamous. But there are some species that have no heterogamy, and the difference is not significant.
Almost all marine algae exhibit alternation of generations. Green and red algae are usually isomorphic, but brown algae have distinct asexual and sexual phases. The latter two types produce both haploid and diploid spores. Some of the red algae can have both kinds of forms. However, only kelp and mosses exhibit heteromorphic alternation of generations. During the course of a lifetime, an organism will go through three stages.
