Question

across

1. point where homologous chromosomes exchange genetic material, visible during crossing over
2. a cell with only one set of chromosomes, such as gametes
3. process where homologous chromosomes exchange genetic material
4. stage when chromosomes line up along the cell equator
5. sex cells like sperm and egg
6. first cell of a new organism formed after fertilization
7. a cell with two sets of chromosomes, one from each parent
8. protein structure that divides the genetic material in a cell by moving chromosomes

down

1. phase when chromosomes are pulled to opposite poles
2. division of the cytoplasm to form two cells
3. stage when crossing over occurs
4. error in meiosis when chromosomes fail to separate
5. each half of a duplicated chromosome
6. chromosomes that are similar in shape, size, and genetic content

Explanation:

1. ACROSS 1: Chiasma is the point where homologous chromosomes exchange genetic material during crossing over.
2. ACROSS 7: Haploid cells have only one set of chromosomes, like gametes.
3. ACROSS 9: Crossing over is the process where homologous chromosomes exchange genetic material.
4. ACROSS 10: Metaphase is when chromosomes line up along the cell equator.
5. ACROSS 11: Gametes are sex cells like sperm and egg.
6. ACROSS 12: Zygote is the first cell of a new organism formed after fertilization.
7. ACROSS 13: Diploid cells have two sets of chromosomes, one from each parent.
8. ACROSS 14: Spindle fiber is the protein structure that divides genetic material by moving chromosomes.
9. DOWN 2: Anaphase is the phase when chromosomes are pulled to opposite poles.
10. DOWN 3: Cytokinesis is the division of the cytoplasm to form two cells.
11. DOWN 4: Prophase I is the stage when crossing over occurs.
12. DOWN 5: Nondisjunction is the error in meiosis when chromosomes fail to separate.
13. DOWN 6: Chromatid is each half of a duplicated chromosome.
14. DOWN 8: Homologous chromosomes are similar in shape, size, and genetic content.

11. DOWN 4: Prophase I
12. DOWN 5: Nondisjunction
13. DOWN 6: Chromatid
14. DOWN 8: Homologous chromosomes
