WebTo put that another way, meiosis in humans is a division process that takes us from a diploid cell—one with two sets of chromosomes—to haploid cells—ones with a single set of chromosomes. In humans, the haploid cells made in meiosis are sperm and eggs. When a sperm and an egg join in fertilization, the two haploid sets of chromosomes form a …

WebDuring this stage, the microtubules, or spindle fibers, pull the homologous chromosomes apart and move them to opposite ends of the cell. Telophase I is next. Here the spindle fibers are broken up, new nuclear membranes form, the chromosomes uncoil, and the cell divides into two daughter cells. The next phase of meiosis is called Meiosis II. cyankssaccWebThe spindle is a structure made of microtubules, strong fibers that are part of the cell’s “skeleton.” Its job is to organize the chromosomes and move them around during mitosis.
