following the same cell in the previous question, how many chromosomes will each nucleus contain at telophase ii?

Explanation:

• Question 3:
• Meiosis I reduces the chromosome number by half.
• If the original cell has 32 chromosomes, after meiosis I (telophase I with cytokinesis), each nucleus will have \(32\div2 = 16\) chromosomes.
• Question 4:
• Meiosis II is similar to mitosis in that it does not further reduce the chromosome number.
• Since after meiosis I each nucleus has 16 chromosomes, after meiosis II (telophase II), each nucleus still has 16 chromosomes.

Answer:

• Question 3: 16
• Question 4: 16
