Detailed explanation-1: -As mentioned previously, meiosis allows the reduction of a diploid cell to a haploid gamete, which can then recombine with another haploid gamete to create a diploid zygote.
Detailed explanation-2: -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-3: -The parent cell undergoes one round of DNA replication followed by two separate cycles of nuclear division. The process results in four daughter cells that are haploid, which means they contain half the number of chromosomes of the diploid parent cell.
