Prophase
Chromosomes condense, spindle fibers form, nuclear envelope breaks down.
Metaphase
Chromosomes align at the cell's center (metaphase plate).
Anaphase
Sister chromatids separate and move to opposite poles.
Telophase
Nuclear envelope reforms, chromosomes decondense.
Cytokinesis
Cytoplasm divides, forming two identical daughter cells.
Prophase I
Chromosomes condense, homologous chromosomes pair (synapsis), crossing-over occurs.
Metaphase I
Homologous pairs align at the center (metaphase plate).
Anaphase I
Homologous chromosomes separate, sister chromatids remain together.
Telophase & Cytokinesis
Two haploid cells form.
Prophase II
Chromosomes condense again.
Metaphase II
Chromosomes align at the center (metaphase plate)
Anaphase II
Sister chromatids separate.
Telophase II & Cytokinesis
Four haploid cells form.
Mitosis
produces 2 diploid (identical) cells; for growth and repair
Meiosis
produces 4 haploid (genetically unique) cells; for sexual reproduction; crossing-over, increasing genetic variation
