Special type of cell division used by sexual reproducing organisms to produce the games, such as sperm or egg cell. Involes two rounds of division that ultimately result in four cells with one one copy of each chromosome(haploid) Additionally prior to division , genetic material from the paternal and material . copies of each from the paternal and material copies of each chromosomes is crossed over creating new combinations of code of each chromosome. Later during fertilization, haploid cells produce meiosis from male to female fuse to create a cell with two copies of chromosome again "ZYGOTE"
