Unformatted text preview: pole and the other two kinetochores of the other homolog are attached to spindle fibers from the opposite pole. Because of this random attachment, the paternal and maternal homologs are randomly aligned and therefore what pole they may be going to is random. A1: a. Cell stage/type # chromosomes # chromatids Ploidy Metaphase I 12 24 2n / diploid Prophase II 6 12 2n / diploid G1 after mitosis 12 12 2n / diploid G2 before mitosis 12 24 2n / diploid Ovum 6 6 n / haploid Zygote in G1 12 12 2n / diploid b. Mitosis is used for repair of damaged cells or to replace cells that are dead. It is used in wound repair and in order to become multicellular from a single cell. Meiosis is used to make diploid cells haploid gametes in an animal, or haploid spores in a plant. A2: The resulting gamete will be 2n, or 46 chromosomes....
