Answer 2

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells.Importance of meiosis:It is a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores.

1. Chromosome number constant:Conservation of specific chromosome number of each species across generations.
2. Maintains individuality of species.
3. Creation of varieties:Increases genetic variability from one generation to the next.Genetic variation is increased by meiosis. During fertilisation , 1 gamete from each parent combines to form a zygote. Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote.
4. Gamete formation and reproduction.Meiosis is the process by which sexually reproducing organisms make their sex cells, sperm and eggs. During meiosis, a specialized cell called a germ cell splits to make four new sex cells, each with half the number of chromosomes as the original germ cell.
5. Meiosis show increased incidences of mutation(sudden changes in genetic material)
6. Crossing over during meiosis results in genetic recombination.
7. In alternation of generation.
8. Maintains diploidity in zygote.
9. Evolution: Meiosis brings variety and variety brings the continuity and flow of evolution.
