Detailed explanation-1: -Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.

Detailed explanation-2: -Genetic variation is increased by meiosis 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.

Detailed explanation-3: -Enables genetic diversity The crossing over or recombination of genes which occurs in meiosis rearranges the alleles present in each chromosome of a homologous pair, allowing the mixing of paternal and maternal genes, either of which can be expressed in the resultant offspring.

Detailed explanation-4: -Meiosis is responsible for the formation of sex cells or gametes that are responsible for sexual reproduction. It activates the genetic information for the development of sex cells and deactivates the sporophytic information. It maintains the constant number of chromosomes by halving the same.

Detailed explanation-5: -Mitosis builds a person with an identical set of chromosomes in every cell. And meiosis generates reproductive cells with new combinations of gene variations. Chromosomes are sometimes gained, lost, or rearranged during meiosis and fertilization, causing people to have genetic disorders.
