Question

1. when does crossing over occur? *

interphase
prophase i
prophase 2
metaphase

1. during which phase do the chromosomes align in the middle of the cell? *

prophase
metaphase
anaphase
telophase

1. during which phase are the chromosomes separated by being pulled apart?

prophase
metaphase
anaphase
telophase

Explanation:

• Question 5: Crossing over occurs during prophase I of meiosis. This is when homologous chromosomes pair up and exchange genetic material.
• Question 6: In metaphase, chromosomes align at the middle (equatorial plane) of the cell.
• Question 7: Anaphase is the stage where sister chromatids (or homologous chromosomes in meiosis I) are pulled apart by spindle fibers.

Answer:

• 5. prophase I
• 6. metaphase
• 7. anaphase
