Meiosis is a type of cell division that involves two main phases: meiosis I and meiosis II. In meiosis I, the cell divides into two daughter cells, each with half the number of chromosomes as the original cell. In meiosis II, these daughter cells divide again to produce a total of four haploid cells, each with a unique combination of genetic material.
The second phase of meiosis is called meiosis II. It follows meiosis I and begins with cells that have been through the first division. In meiosis II, the sister chromatids are separated, resulting in four haploid daughter cells.

The first cell division in meiosis, known as meiosis I, occurs after the DNA in the cell has been replicated during the S phase of the cell cycle. Meiosis I involves the separation of homologous chromosomes.
If homologues are separating, this is likely occurring during the first division of meiosis, known as meiosis I. Homologous chromosomes separate during anaphase I of meiosis.
The longest phase of meiosis is prophase I, which involves chromosome condensation, crossing over, and nuclear envelope breakdown. This phase can be subdivided into early, mid, and late stages, making it the most time-consuming phase in the process of meiosis.

Cytokinesis is the process of dividing the cytoplasm during the M phase of the cell cycle. It typically occurs after nuclear division (mitosis or meiosis) and results in two daughter cells.
The first cell division in meiosis, known as meiosis I, occurs after the DNA in the cell has been replicated during the S phase of the cell cycle. Meiosis I involves the separation of homologous chromosomes.
In meiosis, the stage that is not repeated is interphase. Interphase occurs before meiosis begins and involves the duplication of DNA, preparing the cell for division. After interphase, meiosis consists of two rounds of division—meiosis I and meiosis II—without another DNA replication phase in between.

One that is not dividing or dividing by the process of meiosis.
In mitotic division, chromosomes are arranged individually in the middle of the cell at metaphase, whereas in the first division of meiosis, homologous chromosomes are paired together in the middle. This pairing of homologous chromosomes is known as synapsis and is unique to meiosis.
The phase that has a spindle forming in a haploid cell is meiosis. Meiosis is a type of cell division that produces reproductive cells with half the number of chromosomes as the original cell. During meiosis, a spindle apparatus helps separate the chromosomes into daughter cells.
The interphase occurs before both mitosis and meiosis. During interphase, the cell grows, carries out normal metabolic activities, and duplicates its DNA in preparation for cell division.
