"WebMeiosis (My-oh'-sis) is the process by which a single diploid cell splits into four haploid cells called gametes in preparation for sexual reproduction of an organism. Recall that a diploid cell contains two nearly-identical copies of each chromosome, one from each parent, called a homologous pair of chromosomes. " - How many homologous pairs in meiosis
