Asexual Reproduction vs Sexual Reproduction
(Similarities between Sexual and Asexual Reproduction)
Reproduction is a biological process by which new individuals (progenies) are formed from their parents. There are two types of reproductions in organisms: sexual reproduction and asexual reproduction.
A method of reproduction, usually present in lower animals and plants where progenies are produced from a single parent without the formation of gametes and fertilization. Example: division of bacteria by binary fission, budding of Hydra and yeasts, and vegetative reproduction in plants.
A method of reproduction where the progenies are produced by two parents of separate sexes. These parents produce morphologically and sexually different gametes. The union of gametes results in the formation of zygote. The zygote develops into new progeny.
Difference between Asexual and Sexual Reproduction
|Sl. No.||Asexual Reproduction||Sexual Reproduction|
|1||Asexual reproduction is uniparental. Here the progenies are produced from a single parent.||Sexual reproduction is biparental. Two parents are involved in the production of progenies through sexual reproduction.|
|2||Sex organs are NOT formed.||Sex organs are formed|
|3||Formation of gametes and union of gametes (fertilization) are not involved||Formation of gametes and fertilization are involved|
|4||Zygote is not formed||Zygote is formed by the fusion of gametes|
|5||Meiotic cell division absent, all cell divide mitotically.||Meiosis is essential for sexual reproduction. Meiosis ensures the reduction of chromosome number to haploid number.|
|6||In asexual reproduction, the new progeny arise from a single cell or from a part of the parent||In sexual reproduction, the new progeny arises from the zygote.|
|7||The progeny and the parent will be genetically similar||The progenies will be genetically different from the parents|
|8||Asexual reproduction will not introduce variation in the progeny||Sexual reproduction causes variations in the progeny.|
|9||No evolutionary significance||Sexual reproduction has evolutionary significance in the population|
|10||Usually, large numbers of progenies are produced with asexual reproduction.||Usually, the number of progenies with sexual reproduction will be limited.|
|11||Example: Bacterial fission, budding of yeast, budding of Hydra||Example: Reproduction in human|
