complete the crossword
puzzle.

Explanation:

• 1. Chiasma: The point where homologous chromosomes exchange genetic material during crossing - over.
• 2. Anaphase: Phase when chromosomes are pulled to opposite poles.
• 3. Cytokinesis: Division of the cytoplasm to form two cells.
• 4. Prophase I: Stage when crossing - over occurs.
• 5. Nondisjunction: Error in meiosis when chromosomes fail to separate.
• 6. Chromatid: Each half of a duplicated chromosome.
• 7. Haploid: A cell with only one set of chromosomes, such as gametes.
• 8. Homologous chromosomes: Chromosomes that are similar in shape, size, and genetic content.
• 9. Crossing - over: Process where homologous chromosomes exchange genetic material.
• 10. Metaphase: Stage when chromosomes line up along the cell equator.
• 11. Gametes: Sex cells like sperm and egg.
• 12. Zygote: First cell of a new organism formed after fertilization.
• 13. Diploid: A cell with two sets of chromosomes, one from each parent.
• 14. Spindle fiber: Protein structure that divides the genetic material in a cell by moving chromosomes.
