MEIOSIS I

PROPHASE I

• Each chromosomes duplicates.
• Each chromosomes is visible under a microscope.
• Each duplicated chromosome comes near its duplicated mate.

METAPHASE I

• Pairs of duplicated chromosomes line up in the center of the cell.
• Centromere of each chromatid is attached to the spindle fibers.

ANAPHASE I

• The cytoplasm divides and two new cells form.

MEIOSIS II

PROPHASE II

• Duplicated chromosomes and spindle fibers reappear in new cell.

METAPHASE II

• Duplicated chromosomes move to the center of the cell.

ANAPHASE II

• The centromere divides.
• The chromatids separate and move to opposite ends of the cell.
• Each chromatid now is an individual chromosome.

TELAPHASE II

• The spindle fibers disappear.
• Nuclear membrane forms around each set of chromosomes.

AFTER MEIOSIS II

• The cytoplasm divides.
