Meiosis Diagrams
The following diagrams explain the process of meiosis in eukaryotic cells, beginning with the five phases of prophase.Gametogenesis Meiosis I:
- Five Phases of Prophase Diagram - The five phases of meiotic prophase are leptotene, zygotene, pachytene, diplotene, and diakinesis. During prophase I, chromosomes condense and attach to the nuclear envelope. They also begin their migration to the metaphase plate.
- Metaphase I Diagram - During metaphase I, chromosomes align at the metaphase plate.
- Anaphase I Diagram - During anaphase I, homologous chromosomes move to opposite poles. Unlike in mitosis however, the sister chromatids remain together.
- Telophase I Diagram - During telophase I and cytokinesis, two daughter cells are produced, each with one half the number of chromosomes of the original parent cell.
Gametogenesis Meiosis II:
- Prophase II and Metaphase II Diagram - Chromosomes do not replicate any further in prophase II of meiosis. As chromosomes line up at the metaphase II plate, kinetochores of the sister chromatids point toward opposite poles.
- Anaphase II and Telophase II Diagram - At the end of meiosis II, four daughter cells are produced each with one half the number of chromosomes of the original parent cell.
