Meiosis

Cells undergo a round of DNA replication, forming duplicate chromosomes

• Interphase

• Prophase II

• Anaphase II

• Prophase I

Each chromosomes pairs with its corresponding homologus chromosome to form a tetrad

• Metaphase I

• Telophase I & Cytokinesis

• Prophase I

• Anaphase II

NGSS.HS-LS3-2

Spindle fibers attach to the chromosomes that are arranged across the middle of the cell

• Interphase

• Anaphase II

• Metaphase I

• Telophase II & Cytokinesis

Tags

NGSS.HS-LS1-4

The fibers pull the homologous chromosomes toward opposite ends of the cell

• Metaphase I

• Prophase I

• Anaphase I

• Interphase

Nuclear membranes form; the cell separates into two cells

• Interphase

• Telophase I & Cytokinesis

• Prophase II

• Metaphase I

Meiosis I results in two haploid daughter cells; Meiosis II starts when the cells once again lose their nuclear membranes, chromosomes condense

• Metaphase II

• Prophase II

• Anaphase II

• Interphase

The chromosomes line up across the middle, in a similar way to the metaphase I

• Metaphase II

• Anaphase II

• Prophase II

• Telophase II & Cytokinesis

The sister chromatids separate and move toward opposite end of the cell

• Metaphase I

• Prophase II

• Anaphase II

• Prophase I

Meiosis II results in four haploid daughter cells

• Prophase II

• Anaphase II

• Telophase II & Cytokinesis

• Metaphase II
