WebMay 30, 2024 · During prophase 1 of meiosis I, the homologous pair of chromosomes come very close together and bind tightly to each other so that they almost act as one single unit. This unit is called a bivalent or a tetrad (indicating that each chromosome consists of two sister chromatids so the sum of bivalent is four chromatids).

Therefore … The formation of a bivalent occurs during the first division of meiosis (in the zygotene stage of meiotic prophase 1). In most organisms, each replicated chromosome (composed of two identical sister chromatids ) elicits formation of DNA double-strand breaks during the leptotene phase.
