Why is there no second interphase in meiosis ii?

Cells do not need to replicate their DNA, so there is no need to be in interphase

Explanation:

Interphase is the part of the cell cycle where the cell is not actively dividing. In this stage, the chromatin is decondensed. It is much longer than any stage in mitosos or meiosis, and is the normal state of the cells.

When a meiotic cell is in interphase before it is ready to make daughter cells, it replicates its DNA, ensures that the conditions are favourable for cells to divide (nutrients in good supply, all checkpoints for DNA damage are passed). Then it is able to divide.

Meiosis I generates 2 diploid daughter cells. At the end of this, the cell proceeds straight to meiosis II with no interphase stage, it moves straight to mitosis again.

This is because there is no need for DNA replication or further checks. The purpose of meiosis is to make 4 haploid daughter cells, so the cell will continue until this has happened. The diploid daughter cells made in meiosis I are simply divided again to make 4 haploid cells.
