This physical strand exchange and the cohesion between the sister chromatids along each chromosome make sure that a … 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. These breaks … See more A bivalent is one pair of chromosomes (sister chromatids) in a tetrad.
