Which phase of a normal interphase is missing from interkinesis between the two meiotic divisions?
AThe S phase
BThe G1 phase
CThe G2 phase
DThe M phase
Answer & Solution
Correct answer: A. The S phase
1. The DNA was already copied once, before meiosis I began.
2. Copying it again between the two divisions would defeat the halving.
3. So interkinesis has no S phase and the chromosomes are not duplicated.
4. The cells go straight into meiosis II with the chromatids they already have.
5. The M phase is not part of interphase at all, so it cannot be the missing piece.
