Reproduction is defined as the process of producing offsprings that are biologically or genetically similar to the parent organism. Reproduction enables and ensures the continuity of species, generation after generation.
The two modes of reproduction are
- Sexual reproduction
- Asexual reproduction
Asexual reproduction refers to the type of reproduction in which only a single organism gives rise to a new individual. This does not involve the fusion of gametes, and therefore, the offsprings produced are genetically identical to the parent. The organisms produced by asexual reproduction are less diverse in nature. This type of reproduction is mainly found in unicellular organisms.
Asexual reproduction is further divided into the following categories:
- Binary Fission
Sexual reproduction is the mode of reproduction in which the individuals are formed by the fusion of male and female gametes. Asexual reproduction, on the other hand, is the type of reproduction in which no fusion of gametes takes place and the offspring is genetically identical to the parent.
However, the sexual mode of reproduction is better than the asexual mode. Sexual reproduction provides diversity in the genetic makeup of the offspring. This is due to the combination of genes from two different individuals. However, this is not the case with asexual reproduction since only one parent is involved.
Let us have a look at the advantages of sexual reproduction over asexual reproduction.
Advantages Of Sexual Reproduction Over Asexual Reproduction
- There is diversity in the genetic makeup of the individuals produced by sexual reproduction.
- Since both the parents are involved, the newly formed individuals have the attributes of both.
- Variations are more successful in sexual mode than in asexual one.
- The species produced by sexual reproduction survive more than those produced by asexual reproduction. This is because genetic variations help them to adapt to different environments.
