Is there interphase between meiosis I and meiosis II?
The technical name of this brief "interphase" between meiosis I and meiosis II is interkinesis.

Interkinesis is normally short (it may not even happen) and it's not divided in G1, S or G2, mainly because there is no DNA duplication, which defines the S (Synthesis) phase.
