Interphase Although not a direct part of meiosis, interphase prepares the cell for division. - Labels: Nucleus, DNA replication, Chromosomes, Centrosomes. - Key Events: DNA replication results in duplicated chromosomes consisting of sister chromatids. Meiosis I This is the reductional division where homologous chromosomes separate. Prophase I1. Chromosomes condense and become visible. Homologous chromosomes pair up to form tetrads (labels: homologous pairs, tetrads). Crossing over occurs at chiasmata, exchanging genetic material. Nuclear envelope breaks down. Spindle fibers form and attach to kinetochores. Metaphase I2. Homologous pairs align along the metaphase plate. Spindle fibers from opposite poles attach to each homologous chromosome. Anaphase I3. Homologous chromosomes are pulled apart toward opposite poles. Labels highlight the movement of chromosomes along spindle fibers. Telophase I and Cytokinesis4. Chromosomes arrive at poles and begin de-condensing. Nuclear envelopes may reform. Cell divides into two haploid daughter cells. Meiosis II This division resembles mitosis and separates sister chromatids. Prophase II1. Chromosomes condense again. Nuclear envelope disintegrates if reformed. Spindle fibers reassemble. Metaphase II2. Chromosomes align individually along the metaphase plate. Spindle fibers attach to sister chromatids. Anaphase II3. 3 Sister chromatids are pulled apart toward opposite poles. Telophase II and Cytokinesis4. Chromatids reach the poles and de-condense. Nuclear envelopes re-form. Four haploid cells are produced, each genetically unique. --- Labels and Their Significance in a Meiosis Diagram A labeled diagram emphasizes key structures, including: Chromosomes: The thread-like structures carrying genetic information. Homologous pairs: Matching chromosomes from each parent. Sister chromatids: Identical copies joined by a centromere. Chiasmata: Points of crossing over, critical for genetic variation.
