Prophase-$I$

Vedclass · Answer

(A) Meiosis-$I$ is a reductional division,and its prophase-$I$ is significantly longer and more complex than the prophase of mitosis or prophase-$II$ of meiosis. Prophase-$I$ is further subdivided into five distinct stages: Leptotene,Zygotene,Pachytene,Diplotene,and Diakinesis. These stages involve complex processes such as synapsis,crossing over,and the formation of chiasmata,which require a substantial amount of time to complete. Therefore,Prophase-$I$ is considered the longest phase of meiosis.
