Hence, asexual reproduction is a type of reproduction done by a single organism without production of gametes. It usually results in the production of identical offspring, the only genetic variation arising as a result of random mutation among the individuals. There are three common modes of asexua...

Sexual reproduction evolved from asexual reproduction about 2 billion years ago. Prior to this prokaryotes were reproducing asexually. Sexual reproduction allows organisms to have greater genetic variation which is a key component to natural selection. ...
Spore Formation is a method in Asexual Reproduction. ...When Sporangia burst; minute single-celled, thin or thick walled structures called spores areobtained. Under suitable conditions, they develop into a new Plant. Reproducing using spores is an asexual method. ...
(Found in fungi, algae, protozoa) Occurs when a body part is broken/ broken off and the organism grows a new one Regeneration Ex: earthworm Means of asexual reproduction whereby a single parent breaks into parts the regenerate into whole new individuals ...
The simplest case is found in unicellular plants and animals where there is doubling of cytoplasmic contents and replication of genetic material followed by division of the cell into two parts. Most reproduction in bacteria, blue-green algae, unicellular algae, and protozoa takes place in this way...
Reproduction: Reproduction is described as a biological process in which a new offspring arises from their parents. It enables the continuity of the species. It is characterized as the fundamental feature of all the organisms because each organism exists due to reproduction. ...
