What Is Interkinesis?

By Charlotte Miller

Are you curious to know what is interkinesis? You have come to the right place as I am going to tell you everything about interkinesis in a very simple explanation. Without further discussion let’s begin to know what is interkinesis?

Cell division, a fundamental process in biology, is essential for the growth, development, and maintenance of living organisms. While mitosis and meiosis are the well-known phases of cell division, there is an intriguing yet often overlooked stage called interkinesis. Interkinesis is a brief and mysterious interlude that occurs between the two divisions of meiosis. In this blog, we will explore what interkinesis is, its role in cell division, and the unique characteristics that set it apart from other phases.

What Is Interkinesis?

Interkinesis is the intermediate phase that separates the first meiotic division (meiosis I) from the second meiotic division (meiosis II). Meiosis is a specialized form of cell division that reduces the chromosome number by half, leading to the formation of haploid cells (cells with half the number of chromosomes as the parent cell). Interkinesis is exclusive to meiosis, and it has distinct characteristics that differentiate it from the more familiar phases of mitosis and meiosis.

Key Characteristics Of Interkinesis

Intercellular Activity: Unlike other phases of meiosis, interkinesis is relatively passive in terms of cellular activity. It is primarily a resting phase.

  1. Absence of DNA Replication: DNA replication does not occur during interkinesis. The DNA content remains constant, as it does not undergo the duplication that takes place in interphase preceding meiosis.
  2. No Chromosome Condensation: Chromosomes remain decondensed and in their chromatin form throughout interkinesis. This is in contrast to other stages of meiosis when chromosomes undergo condensation for segregation.
  3. Short Duration: Interkinesis is typically a very short phase compared to other stages of meiosis. It is merely a transient pause in the process.

Role Of Interkinesis

The primary role of interkinesis is to allow the cell to prepare for the second meiotic division (meiosis II). Although it may seem uneventful, this phase serves several crucial functions:

  1. Relaxation: By maintaining decondensed chromosomes, interkinesis allows the cell to “rest” and recover from the previous division.
  2. Reorganization: It provides an opportunity for the cell to reorganize cellular components and prepare for the final stage of meiosis.
  3. Final Segregation: The preparations made during interkinesis are essential for the second meiotic division, where the sister chromatids are separated, leading to the formation of four haploid daughter cells.
  4. Ensuring Genetic Diversity: Meiosis aims to generate genetic diversity through recombination and random assortment of chromosomes. Interkinesis sets the stage for the final reshuffling of genetic material during meiosis II.


Interkinesis, the brief and often overlooked interlude between the two divisions of meiosis, is a crucial phase in the formation of haploid cells. Although it may appear uneventful compared to other stages of meiosis, interkinesis plays a vital role in ensuring the accurate segregation of chromosomes and the generation of genetically diverse offspring. Its distinct characteristics, such as the absence of DNA replication and chromosome condensation, make it a unique and fascinating phase in the complex process of cell division.


What Is Called Interkinesis?

Interkinesis, also known as interphase II, is a period of rest that certain species’ cells experience between meiosis I and meiosis II. During interkinesis, no DNA replication occurs; nevertheless, replication occurs during the interphase I stage of meiosis.

Which Phase Is Called Interkinesis?

Interkinesis is the stage that occurs in between meiosis–I and meosis–II. The stage between two meiotic divisions is called interkinesis and is generally short lived and followed by prophase II of meiosis II. Here, the cell undergoes a period of rest. No DNA replication and no gene duplication occurs during this stage.

What Is Interkinesis Followed By?

Interkinesis is followed by prophase II. It is the resting period for the cells of divisions before they undergo the stage of meiosis II. No DNA replication occurs during the Interkinesis or Interphase II.

Is Interkinesis And Cytokinesis Same?

After the first cytokinesis, there may be a short period of rest before the new cell proceeds to meiosis II. This resting period is called interkinesis or interphase II. It is called interphase II because the first interphase (i.e. interphase I) takes place before the cell enters meiosis I.
