How many homologous pairs in meiosis

WebO Haploid cells have one full set of chromosomes (no homologous pairs), while cells have two sets. O All of the above. 2. What distinguishes haploid cells from diploid cells? * O Haploid cells have homologous pairs of chromosomes, but half the number compared to diploid cells. O Haploid cells have a mixture of homologous pairs and unpaired ... 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.
