Interkinesis, the interval between meiosis I and meiosis II, is unusual because it lacks:

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. _Source: OpenStax Biology for AP(R) Courses (CC BY 4.0), Ch 11 'Meiosis and Sexual Reproduction', sections 11.1-11.2_
