Detailed explanation-1: -Meiosis is important for creating genomic diversity in a species. It accomplishes this primarily through 2 processes: independent assortment and crossing over (recombination).

Detailed explanation-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. This process is required to produce egg and sperm cells for sexual reproduction.

Detailed explanation-3: -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.

Detailed explanation-4: -Gene Transmission in Mitosis Indeed, apart from random mutations, each successive duplicate cell will have the same genetic composition as its parent, due to the inheritance of the same chromosome set and similar biological environment.

Detailed explanation-5: -Mitosis produces genetically identical daughter cells, each containing a complete copy of the parent cell’s DNA. Meiosis produces four genetically non-identical daughter cells, which increases genetic variation among gametes (and, therefore, genetic diversity in the population).
