Detailed explanation-1: -Because meiosis creates cells that are destined to become gametes (or reproductive cells), this reduction in chromosome number is critical-without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes!
Detailed explanation-2: -We now know that meiosis is the process of chromosomal reduction which allows the production of haploid germ cells necessary for sexual reproduction. Meiosis is furthermore important for its role in enabling genetic diversity and facilitating the repair of genetic defects through recombination.
Detailed explanation-3: -Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs). However, sexual reproduction includes fertilization (the fusion between gametes), which is not part of the meiotic process.
