WebSolution. Verified by Toppr. Correct option is D) The two homologous chromosomes do not completely separate but it remains attached together at one or more points as indicated by X arrangements known as Chiasmata. The displacement of Chiasmata is termed as terminalization which is completed in Diakinesis stage. WebThe final stage of meiotic prophase I is diakinesis. This is marked by terminalisation of chiasmata. During this phase the chromosomes are fully condensed and the meiotic spindle is assembled to prepare the homologous chromosomes for separation. Diakinesis represents end of prophase I and transition to metaphase. trey simmerman wv attorney
