Before mitosis and meiosis, DNA is loose in the form of chromatin, then it coils into chromosomes right before the mitosis and meiosis.
A nucleus is signals the rest of the cell that the cell is ready to undergo meiosis, in which case the chromosomes begin to condense with the help of histones, which is the beginning of prophase I of meiosis.
After meiosis II, each cell will have a haploid number of chromosomes, which means they will have half the number of chromosomes compared to the original cell before meiosis.
The pairing of homologous chromosomes before nuclear division occurs in meiosis. Meiosis is a type of cell division that results in the formation of sex cells (sperm and egg cells) with half the number of chromosomes as the parent cell.
Meiosis is known as a reduction division. The total number of chromosomes present prior to meiosis is reduced in half at the end of meiosis. In this case 12 pairs of chromosomes before meiosis (a total of 24 chromosomes) becomes 12 chromosomes (one of each pair) at the end of meiosis.
DNA replicates and forms tetrad—APEX.

Well first the sperm has to be made by meiosis. Then it has to get to the egg and enter it [If you catch my drift.] Then after that the nucleus of both the sperm and the egg disappear and the chromosomes of both join together and a new nucleus forms. This creates a new dipliod cell, or a new organism in other words.
Interphase before Prophase I.
Yes duplication of chromosomes occurs during the first stage of meiosis or during prophase.
Meiosis is known as a reduction division. The total number of chromosomes present prior to meiosis is reduced in half at the end of meiosis. In this case 12 pairs of chromosomes before meiosis (a total of 24 chromosomes) becomes 12 chromosomes (one of each pair) at the end of meiosis.
In meiosis, chromosomes replicate during interphase before the start of cell division. This process ensures that each daughter cell will receive the correct number of chromosomes.
