WebFig. 1 Before meiosis occurs, each chromosome must be duplicated. When a chromosome is duplicated, the resulting attached, identical chromosomes are referred to as sister chromatids. MEIOSIS I: Meiosis I is where 1 diploid parent cell divides into 2 haploid cells. Prophase: In this stage, homologous chromosomes pair up to form tetrads . Web18. If a cell has 84 chromatids at Metaphase of Mitosis, how many chromosomes would you observe in each of the two nuclei during late Telophase of Mitosis? A.
