At the end of meiosis 2 cells are haploid. Do they go through replication of s phase after this? Are the resulting chromosomes therefore replicated or unreplicated? Does this make them diploid again?

No. Nothing is replicated, this is the process of cells dividing.

Explanation:

Once the cells are haploid, this means they are now two identical cells. This is at the end of Meiosis I, which can also be called telophase I. Once the cells start meiosis II, they go through prophase II which is the same as prophase I, the only difference is the fact there are now two cells dividing. Both cells go through the same process they did in meiosis I, each cell will divide into another cell. This means by telophase II, also known as the end of meiosis II, the two cells are now four diploid cells.

Haploid cell: Has 1 copy of each chromosome gametes. Results from Meiosis.

Diploid cell: Has 2 copies of each chromosome, 1 from Dad, 1 from Mom. Results from Mitosis. (Meiosis II).

condensation. good luck!
