1. Meiosis
How Sex Cells Form

2. DNA Chromosome
Nucleus
Cell Membrane
Cytoplasm
Parent Cell

3. Before Meiosis Begins: The Cell Replicates its DNA

4. Step 1: The Chromosomes Condense

5. Each Chromosome is made up of two Chromatids

6. Chromatids
Step 1: Homologous Chromosomes Pair and Line up Along the Cells Equator

11. Step 2: Homologous Chromosomes Separate and are Pulled to Opposite Sides of the Cell

15. Step 3: The Cell Divides

19. Each Cell Contains One Member of Each Chromosome Pair

20. Step 4: The Chromosome Line Up at Each Cells Equator

22. Step 5: The Chromatids Pull Apart and Move to Opposite Sides of the Cell

26. Step 6: The Cells Divide as Before

28. Each Daughter Cell (Gamete) Has Half the Number of Chromosomes Present in the Parent Cell
