Interkinesis or interphase II is a period of rest that cells enter during meiosis. It is the abbreviated interphase that occurs between meiosis I and II. No DNA replication occurs during this stage of Meiosis. Many plants skip telophase I and interkinesis, going immediately into prophase II. Each chromosome is still composed of two chromatids.
What else can I help you with?
What event does interkinesis lack compared to premeiotic interphase?
Interkinesis lacks DNA replication that occurs in premeiotic interphase. Interkinesis is a short interphase stage that follows the first meiotic division, where there is no replication of DNA as the chromosomes are already duplicated from the previous S phase.
What is the period of time between the first and second meiotic divisions?
The period of time between the first and second meiotic divisions is known as interkinesis. Interkinesis is a brief interphase that occurs between the two meiotic divisions in which DNA replication does not occur.
Following telophase 1 of meiosis there is a period called?
interkinesis, which is a brief period between the end of telophase I and the beginning of prophase II. During interkinesis, the cell prepares for the next division by briefly resting and allowing time for the chromosomes to decondense.
What is the difference between interphase and interkinesis?
The interphase consists of 3 parts: presynthesis [growth 1=G1]- in which proteins are synthesized, synthesis [S] in which the DNA strands are duplicated and postsynthesis [growth 2=G2] in which contractile proteins are synthesized. Interkinesis lacks the S phase because there is no need for a duplication of DNA, as the intent of meiosis is to produce haploid cells.
Is Interkinesis is the most important process that increases variety in human gametogenesis?
No, interkinesis has nothing to do with genetic variation. The two features of meiosis that increase genetic variation in gametogenesis are (a) crossing over during prophase I, and (b) the independent assortment of chromosomes during anaphase I and anaphase II.

Following telophase 1 of meiosis there is a period called which is similar to interphase except no replication of genetic material occurs?
Following telophase I, cells may or may not enter a stage known as interkinesis or interphase II. Interkinesis is similar to interphase I, but with no genetic material duplication.
Does replication occur during interkinesis?
No because the chromosomes are already duplicated No. DNA replication does not occur during interkinesis. Interkinesis is a breif rest period between meiosis I and meiosis II. In some species, daughter cells do not form, and meiosis II follows right after meiosis I. No. Because at this point, the first division of meiosis is complete. The cell now rests for a bit before beginning the second meiotic division. During this period, called interkinesis, the nuclear membrane in each of the two cells reforms around the chromosomes. In some cells, the spindle also disintegrates and the chromosomes relax (although most often, the spindle remains intact).

What is interkinsis?
Interkinesis is the period between the first and second divisions in meiosis. Meiosis is a special type of cell division of genetic material (DNA). Meiosis produces genetic diversity.

No, interkinesis has nothing to do with genetic variation. The two features of meiosis that increase genetic variation in gametogenesis are (a) crossing over during prophase I, and (b) the independent assortment of chromosomes during anaphase I and anaphase II.
What is the period called after telophase 1?
In cell division, the period after telophase 1 is called cytokinesis. It occurs at the end of either mitosis and meiosis,

During which parts of interphase does DNA replication occur?
No because the chromosomes are already duplicated No. DNA replication does not occur during interkinesis. Interkinesis is a breif rest period between meiosis I and meiosis II. In some species, daughter cells do not form, and meiosis II follows right after meiosis I. No. Because at this point, the first division of meiosis is complete.

The order of steps to mitosis?
PMAT is the way that I learned these and it really helps to use it.Mitosis is simply described as having four stages—prophase, metaphase, anaphase, and telophase; the steps follow one another without interruption.The entire four-stage division process averages about one hour in duration, and the period between cell divisions, called interphase or interkinesis, varies greatly but is considerably longer.
