Study Notes

Phases of Meiosis

Interphase: Genetic material duplicates, condenses into chromosomes; preparation for meiosis occurs.
Prophase I: Homologous chromosomes pair up; crossing over occurs, increasing genetic diversity.
Metaphase I: Homologous chromosomes attach to the spindle apparatus; they line up at the cell's equator.
Anaphase I: Homologous chromosomes are separated and pulled to opposite poles of the cell.
Telophase I: New nuclei form around separated chromosomes; cytokinesis starts, leading to two daughter cells.
Prophase II: Chromosomes condense again; no replication occurs after Meiosis I.
Metaphase II: Spindle apparatus attaches to centromeres of chromosomes; chromosomes align at the equator for separation.
Anaphase II: Sister chromatids are pulled apart and move to opposite poles of each cell.
Telophase II: Formation of two new nuclei; cytokinesis results in four distinct daughter cells.
Cytokinesis: Cytoplasm divides at the end of each meiosis stage, leading to the formation of new daughter cells and gametes.

Description

Test your understanding of the eight key phases of meiosis, from Interphase through to Cytokinesis. This quiz will cover each stage's significance and processes that ultimately lead to the formation of four distinct daughter cells.
