Bivalents in meiosis are tetrads.

* Bivalents consist of a pair of homologous chromosomes and a total of four chromatids, known as sister chromatids.

These four chromatids are together known as tetrads.

* It is found to occur during the first step of meiosis, the pachytene stage of prophase I.

* Next, they form chiasmata to bring about recombination between homologous chromosomes.
