During the stages of meiosis I, homologous chromosomes pair and are segregated into separate cells. These stages include prophase I, metaphase I, anaphase I and telophase I. Professor Wolfe will explain what happens durring each of these different phases. He will focus specifically on what is happening with the cell's chromosomes during these phases. In prophase I, homologous chromosomes synapse and form tetrads. In metaphase I, homologous chromosomes organize and line up. In anaphase I, homologous chromosome pairs separate, and in telophase I, a cleavage furrow forms, creating two cells. Each created cell has one chromosome from each homologous pair. During the stages of meiosis II, the doubled chromosomes are divided and move into separate cells as in mitosis. Meiosis II is also made up of stages (prophase II, metaphase II ...
