Hint: It is the separation of one of the two identical halves of a replicated chromosome. Chromosome first replicates itself during cell division so after that each daughter cell receives a whole set of chromosomes for itself. After DNA replication, it is joined at the centromere with its counterpart.

Complete answer:
Meiosis II is smaller than a typical mitotic division because the prophase of this division becomes shorter. This division keeps the number of chromosomes produced at the end of the reduction division. It is similar to mitosis and is often termed as homotypic or equational division. It differs from each other in the linkage group due to crossing over.
Meiosis II has four stages within itself;
1. Prophase II– The chromosomes condense and cell organelles disappear in this stage.
2. Metaphase II– The chromosomes get aligned at the equator to form the metaphase plate.
3. Anaphase II– This is the stage where the chromosomes are pulled apart and thus separated.
4. Telophase II– The condensed chromosomes revert back into an undifferentiated lump.

Meiosis II performs separation of chromatids which are the separation of one of the two similar halves of a replicated chromosome.

Note:
Meiosis II is important to separate the chromatids of dead chromosomes so to bring haploidy in DNA or Deoxyribonucleic acid. It also maintains the number of chromosomes in the daughter cells after Meiosis-I but increases the number of daughter cells. Mechanics of meiosis-II is identical to mitosis just the difference is that each diffusing cell has only one set of homologous chromosomes and hence each cell has \[50\% \] of the number of sister chromatids.
