At what stage of meiosis does tetrad splitting occur?

Meiosis is the process of division of germ cells, as a result of which a haploid (single) set of chromosomes is obtained in gametes. In meiosis, there are two divisions in which the phases are repeated: prophase, metaphase, anaphase and telophase. The splitting of chromosomes occurs in anaphase.
Before the onset of meiosis, the chromosomes are doubled, and in the prophase of 1 division, homologous chromosomes are conjugated, that is, intertwined, resulting in the formation of tetrads (groups of four chromosomes). Their cleavage occurs in the anaphase of 1 division of meiosis.
