Reproduction is defined as the process of producing offspring that are biologically or genetically similar to the parent organism.
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. gamete fusion is not involved and thus the offspring produced are genetically identical to the parent. In nature the organisms which are produced via asexual reproduction is very less. In unicellular organisms mostly this reproduction is found.
Asexual reproduction is divided into three. They are
- Binary Fission
The mode of reproduction in which individuals are formed by the fusion of male and female gametes is known as sexual reproduction. Whereas asexual reproduction 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.
