Interkinesis, the interval between meiosis I and meiosis II, is unusual because it lacks:
AAn S phase
BA G2 phase
CA spindle
DA G1 phase
Answer & Solution
Correct answer: A. An S phase
1. If DNA were copied again between the divisions, the chromosome number would not fall.
2. So the interval must skip replication.
3. Interkinesis lacks an S phase, so chromosomes are not duplicated.
4. That is exactly why meiosis halves the chromosome count.
