**Question 1: Chromosome Activity** *Question:* Which of the following is/are true about the chromosomes depicted in the picture? *Diagram Description:* The left diagram shows two pairs of homologous chromosomes with similar color coding indicating genetic similarity. The right diagram shows crossing over where sections of the chromosomes exchange genetic material, identified with different color patterns. *Options:* - I and II - I, II, and III - I only - I, II, III, and IV - No answer *Statements:* I. Tetrad formation of homologous pairs II. Crossing over and genetic recombination III. Sister chromatids are fusing together IV. Deletion and insertion of genetic codes Annotated answer: 27 --- **Question 2: Events in Mitosis** *Question:* The following statements are the events that occur during Mitosis. Which of the following is the correct order of these events? *Events:* I. The bonds connecting the sister chromatids weaken II. Centrioles move to the opposite poles III. Nuclear membrane starts to disintegrate IV. Sister chromatids separate V. Chromosomes are at the equator of the cell VI. Two daughter cells are created Annotated answer: 28 **Chromosome Arrangements in Meiosis and Mitosis** **Question 1:** *In which of the following phases does this specific arrangement of chromosomes occur?* ![Chromosome Diagram](image) - No answer - Prophase II - All are correct - Prophase of Mitosis - Prophase I **Answer Explanation:** The handwritten selection indicates "Prophase I" as the correct answer. In this phase, homologous chromosomes pair and form tetrads, sometimes exchanging genetic material through crossing over. **Question 2:** *Which of the following is/are true about the chromosomes depicted in the picture?* ![Chromosome Diagram](image) I. Tetrad formation of homologous pairs II. Crossing over and genetic recombination III. Sister chromatids are fusing together IV. Deletion and insertion of genetic codes - I and II - I, II, and III - I only - I, II, III, and IV **Answer Explanation:** The handwritten selection indicates "I and II" as the correct answers. Tetrad formation and crossing over occur in Prophase I of meiosis, essential for genetic diversity. **Diagram Explanation:** The diagrams show chromosomes in a typical pairing during the early stages of meiosis, where genetic material is exchanged, crucial for proper genetic segregation.
