Prophase I precedes metaphase I, a stage that features homologous chromosomes aligning along a single plane in the center of the cell. The outcome of meiosis is the creation of daughter cells, either sperm or egg cells. In the gametes, a different form of cell division occurs called meiosis. Stages of Prophase Leptotene The chromosomes begin to condense and are attached to the nuclear membrane via their telomeres Zygotene Synapsis begins with. This stage then ends with the disintegration of the nucleolus and the nuclear membrane. The body is made up of trillions of somatic cells with the capacity to divide into identical daughter cells facilitating organismal growth, repair, and response to the changing environment. Thus, this stage is important to increase genetic variation. Synapsis occurs (a pair of homologous chromosomes. Chromosomes condense and attach to the nuclear envelope. There are two stages or phases of meiosis: meiosis I and meiosis II. Mitosis is a process of cell division that results in two genetically identical daughter cells. Overview of the Stages of Meiosis Interphase. You need to know the relationship between mutation, cell cycle, and uncontrolled cell growth. Prophase I highlights the exchange of DNA between homologous chromosomes via a process called homologous recombination and the crossover at chiasma(ta) between non-sister chromatids. Cells divide and reproduce in two ways: mitosis and meiosis. You need to know how mitosis and meiosis lead to genetic variation. Ask students to model each stage of mitosis using the. This stage is characterized by having five sub-stages namely leptotene, zygotene, pachytene, diplotene and diakinesis. Each part will represent a stage in mitosis: Interphase, Prophase, Metaphase, Anaphase, and Telophase. Prophase I is the first stage in meiosis I. Each of these phases is designated as I or II depending where it occurs, i.e. Moreover, the chromosomes in metaphase of mitosis can be a diploid set or haploid set, but the chromosomes in metaphase of meiosis II always consist of a. These are prophase, metaphase, anaphase and telophase. There are two successive nuclear divisions: meiosis I and meiosis II. Meiosis is a specialized form of cell division that ultimately gives rise to non-identical sex cells. The first stage in the first meiotic division of meiosis characterized by having five sub-stages namely leptotene, zygotene, pachytene, diplotene and diakinesis, and essential mainly for the exchange of DNA between homologous chromosomes via a process called homologous recombination and the crossover at chiasma(ta) between non-sister chromatids
