    Study Notes

    Meiosis Overview

    • Anaphase I involves the separation of homologous chromosomes moving towards opposite poles of the cell.
    • During Telophase II, chromosomes reach the poles, and the nuclear envelope reforms, resulting in the formation of four genetically distinct cells.
    • Prophase II is characterized by the re-condensation of chromosomes without further DNA replication, and the nuclear envelope breaks down again.
    • The first Polar Body typically degenerates and does not participate in reproduction, serving as a means of discarding excess genetic material.
    • Metaphase II features chromosomes lining up along the metaphase plate, similar to mitosis, with spindle fibers attached to the centromeres.
    • Cytokinesis during Telophase I results in two daughter cells, each haploid but still consisting of duplicated chromosomes.
    • In meiosis II, Secondary Spermatocytes or oocytes undergo division without the DNA being copied again, maintaining the chromosome number.
    • Anaphase II is marked by the separation of sister chromatids, which are pulled to opposite poles of the cell.
    • Cytokinesis in Telophase II produces four haploid cells in males known as spermatids.
    • Ootids undergo maturation to become functional ova or eggs in females.
