WebBivalent formation plays role in crossing over which is responsible for genetic variations hence responsible for evolution. What is bivalent condition of prophase? During meiosis-I, in zygotene phase of prophase-I, the bivalent chromosomes clearly appear as tetrads. Here, the homologous chromosomes align together to form tetrads.
