Meiosis is a type of cell division that halves the genetic material in cells.it makes haploid gametes (sex cells)
Start with 1 diploid cell with two pairs of homologous chromosomesInterphase - Just before meiosis, DNA replicates, so cells which contained two copies of each chromosome now have four. Chromosomes are not yet visibleEarly Prophase - Chromosomes become visible. Centrioles move to opposite sides of the cell. Each homologous pair of chromosomes comes together to form a bivalentLate Prophase - Each chromosome in a bivalent forms two chromatids. Genetic mixing occurs. The points of crossover (Chiasmata) become visibleMetaphase - The bivalents arrange themselves on the equator of the spindleAnaphase - The Chromatid pairs from each homologous chromosome split apart and move to opposite poles of the cellTelophase - Cytokinesis begins, two new cells form, each has two copies of each chromosome. These chromosomes are genetically different from those in the original cellSecond Division
Prophase 2 - A new spindle forms at right angles to the first Metaphase 2 - Chromosomes, each of which is a pair of chromatids, align themselves on the equator of the spindleAnaphase 2 - Chromatids are pulled apart to form two chromosomes that then move to opposite poles of the cellTelophase 2 - Cytokinesis begins. Four haploid cells, each with only a single chromosome, have been formed. Each chromosome is genetically different.
