    Non-random alignment of chromosome pairs.

    Explanation:

    Meiosis is when the mother cell or the diploid cell replicates into four haploid cells and divides twice; leaving just two haploid cells that contains only half the number of chromosomes.

    Through meiosis, we get the gametes which are the cells that we use to fecund and reproduce ourselves (ovules and sperm); each cell contains half the chromosome content. To allow the combination of genetic information by cross-linking the chromosomes there need to be 23 chromosomes from the father and 23 from the mother to form one individual with 46 chromosomes.

    Leaving us with non-random alignment of chromosome pairs as if it was random that would mean that it wouldn't matter how many chromosomes each parent provides, also, the cells have to be haploid in order to continue the process.
