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.
step 1 ( prophase) step 1 ( prophase)
No, crossing over occurs during prophase 1 of meiosis, not prophase 2.
Meiosis 1: Prophase 1, Metaphase1, Anaphase 1, Telophase 1. Meiosis 2: Prophase 1, Metaphase 2, Anaphase 2, Telophase 2. Makes 4 daughter cells that contain 4 chromosomes each.

prophase 1
Crossing over occurs during Prophase I of meiosis.
During prophase of mitosis, the number of cells remains constant. Prophase is the first stage of mitosis where the nucleus condenses and the chromosomes become visible, but the cell itself does not divide yet.
Tetrads line up in the middle of the cell during metaphase I of meiosis. This is when homologous chromosomes align along the equator of the cell, creating tetrads with pairs of homologous chromosomes.
Prophase 1 , Metaphase 1 , Anaphase 1 , Telophase 1 & Cytokinesis, Prophase 2, Metaphase 2, Anaphase 2, Telophase 2 & Cytokinesis
The steps to Meiosis are ;~ Prophase 1~ Metaphase 1~ Anaphase 1~ Telephase 1~ Prophase 2~ Metaphase 2~ Anaphase 2~ Telephase 2
In prophase I of meiosis, chromosomes condense, homologous chromosomes come together and may exchange genetic material through crossing over, and the nuclear membrane breaks down. These events are important for genetic recombination and the formation of genetically diverse gametes.
