Meiosis 1 and Meiosis 2

In ___________ DNA coils tightly into chromosomes and spindle fibers appear. Then, the nucleolus and nuclear membrane disassemble.

• Prophase 1

• Anaphase 1

• Prophase 2

During ____________ tetrads line up randomly along the midline of the dividing cell. Spindle fibers then attach to the centromere from one pole to the centromere of a homologous chromosome. Spindle fibers from opposite poles attach to one other homologous pair.

• Metaphase 2

• Metaphase 1

• Prophase 2

In this stage of meiosis, each homologous chromosome moves to an opposite pole of the dividing cell.

• Anaphase 2

• Telophase 1

• Anaphase 1

In this stage of meiosis, chromosomes reach the opposite ends of the cell and cytokinesis begins.

• Telophase 1

• Telophase 2

• Telophase 3

In this stage of meiosis, spindle fibers form and begin to move the chromosomes toward the midline of the dividing cell.

• Prophase 1

• Prophase 2

• Metaphase 1

In this stage, chromosomes move to the midline of the dividing cell with each chromatid facing opposite poles of the dividing cell.

• Prophase 2

• Anaphase 2

• Metaphase 2

In this stage of meiosis, chromatids separate and move toward opposite poles of the cell.

• Anaphase 2

• Anaphase 3

• Anaphase 1

In this stage of meiosis, a nuclear membrane forms around the chromosomes in each of the four new cells.

• Telophase 2

• Anaphase 1

• Metaphase 1
