Study Notes

Stages of Meiosis

Prophase I: Chromosomes condense, nuclear envelope disintegrates; crossing-over occurs, allowing genetic recombination between homologous chromosomes.
Metaphase I: Homologous chromosome pairs align at the cell's equatorial plane, preparing for separation.
Anaphase I: Homologous chromosomes are pulled apart to opposite poles of the cell, reducing the chromosome number by half.
Telophase I and Cytokinesis: Chromosomes reach the poles of the cell, and the cytoplasm divides, resulting in two haploid cells with replicated chromosomes.
Prophase II: A new spindle apparatus forms around the chromosomes in the two haploid cells, readying them for the second meiotic division.
Metaphase II: Chromosomes, consisting of sister chromatids, align at the equator of each haploid cell, similar to metaphase in mitosis.
Anaphase II: Centromeres split, allowing sister chromatids to move to opposite poles of the cell, ensuring each new cell will receive identical genetic material.
Telophase II and Cytokinesis: Nuclear envelopes reform around each set of chromosomes; the cytoplasm divides, resulting in four genetically diverse haploid daughter cells.
