DNA is copied
The tetrads are pulled apart.
Another way to increase genetic diversity is the process referred to as anaphase one. The is the third stage of meiosis, which is where chromosomes are loosened.
Meiosis has two divisions, called meiosis I and meiosis II. Meiosis I involves separating homologous chromosomes, while meiosis II involves separating sister chromatids. Mitosis, on the other hand, only has one division where the goal is to produce two daughter cells with identical genetic information to the parent cell.

In prophase I of meiosis, chromosomes can be seen under an optical microscope. The chromosomes appear shorter and thicker. Meiotic division happens in two stages.

Meiosis does in fact divide twice, once in meiosis I (cytokinesis) and meiosis II (cytokinesis) basically it divides into four daughter cells at the end of meiosis. Two from meiosis I and four in meiosis II
No, the nucleus does not divide in meiosis 1 and then again in meiosis 2. In meiosis 1, the nucleus divides once to reduce the chromosome number in the cell, resulting in two daughter cells. In meiosis 2, the two daughter cells from meiosis 1 divide again to form a total of four haploid daughter cells.
Meiosis consists of two separate divisions : meiosis 1 and meiosis 2Meiosis 1 : members of each homologous pair of chromosomes separate.Meiosis 2 : the two cromatids of each chromosome separate.
