Final answer:
The phase of mitotic interphase that is missing from meiotic interkinesis is G2, where no new DNA synthesis occurs between the two meiotic divisions.
Step-by-step explanation:
The phase of mitotic interphase that is missing from meiotic interkinesis is G2. Mitotic interphase is the stage of the cell cycle where cells prepare for division, and it consists of three parts: G1 (first gap phase), S (synthesis phase), and G2 (second gap phase). During mitosis, these stages lead to the actual division of the cell. However, in meiosis, which consists of two consecutive rounds of division (meiosis I and meiosis II), the interkinesis stage between meiosis I and II is analogous to interphase but typically lacks a proper G2 phase. Therefore, DNA is not replicated again before meiosis II, as the cell has already duplicated its DNA during the preceding S phase of interphase before meiosis I.
