    i have doubt in question no 7 and 13. if crossing over takes place in pachytene so chiasmata should also visible in pachytene. but here answer is diplotene. i am not getting this concept.

    • irum

      The chiasmata become visible during the diplotene stage of prophase I of meiosis, but the actual “crossing-overs” of genetic material are thought to occur during the previous pachytene stage

    I have a doubt about que 6 and que 7…daughter chromosome start moving towards the respective poles in late anaphase
    and about que 7 that- chismata is a point of crossing over…so if crossing over take place in pachytene stage then chismata should be also in pachytene?

    • Ankita

      For question 6-) daughter chromosome starts moving towards opposite poles in anaphase and in late anaphase they look like the diagram from question-1
      For question-7) chiasmata is the point of crossing over but it is formed when linked bivalents are seperated but remains intact from one point i.e. chiasmata hence formed in diplotene.

    Very important question.it is the most necessary commonly uses in our next study. Thanks
