WebJul 17, 2024 · Interphase. Ed Reschke/Getty Images. There are two stages or phases of meiosis: meiosis I and meiosis II. Before a dividing cell enters meiosis, it undergoes a period of growth called interphase. At the end of the meiotic process, four daughter cells are produced. G1 phase: The period prior to the synthesis of DNA.

WebMeiosis is a specialized type of cell division that reduces the chromosome number by half ( during Meiosis i ), creating four haploid cells ( during M I & M ii,) each genetically distinct from the parent cell that gave rise to them.

WebJun 11, 2024 · Function of Meiosis. Meiosis is necessary for many sexually-reproducing animals to ensure the same number of chromosomes in the offspring as in the parents. The act of fertilization includes two cells fusing together to become a new zygote. If the number of alleles of each gene is not reduced to 1 in the gametes that produce the zygote, there ...
