In a process similar to mitosis, a cell forms two daughter cells that each have a single set of chromosomes, half the total number in the original cell. Step 2: Each of the two daughter cells is divided into two making four gametes.This step is called Meiosis II but it is really the same process as mitosis. Gametes only contain one copy of each gene, but the cell they were made from contained two varieties of each gene.The genes in each gamete are chosen randomly from each pair of alleles during meiosis.tep 2: Each of the two daughter cells is divided into two making four gametes.
