Tetrads form occurs only in meiosis.
In the prophase of mitosis, the nuclear membrane disappears, the chromosomes of the cell undergo morphological changes.
The centrosome divides into two centrioles and microtubules appear.
Prophase I of meiosis is a long period in which the chromosomes present a particular behavior, essentially different from that observed in mitosis.
The main difference between mitotic and meiotic prophase is that here the chromosome pairs unite and form synapses.
Each functional unit is a tetrad (2 chromosomes) or, what is the same, 4 chromatids.
That is, the chromosomes are more tightly wound and the chromatids become visible; the homologous pair is now called the tetrad (made up of four chromatids).
Therefore, we can that comparing prophase I of meiosis with prophase of mitosis, tetrads form occurs only in meiosis.
