Asexual reproduction produces offspring that are genetically identical to the parent, whereas sexual reproduction produces a similar, but genetically unique offspring. In sexual reproduction, meiosis produces haploid gametes that fuse during fertilization to produce a diploid zygote figure below.

What is reproduction?
Reproduction is the process by which organisms, such as plants and animals, produce offspring. In this process, organisms replicate themselves and bear offspring in order to ensure the survival of their species. Reproduction can be a sexual or an asexual act, dependent on the species. In sexual reproduction, the formation of a new organism is created by the union of a male and female gamete, or reproductive cell. Organisms that partake in sexual reproduction mostly include animals and certain plants. In asexual reproduction, a single organism generates a new organism. This organism is genetically identical to its parent. Organisms that partake in asexual reproduction include most fungi, bacteria and certain plants. Cell reproduction usually includes the division of a cell into two identical parts or into four different parts. These cell divisions are, respectively, known as mitosis and meiosis.
What is its significance?
1. It helps to maintain the number of species.
2. It ensures continuity of similar kinds of individuals.
3.It helps in transfer of characters from one generation to the other.
