  • priyanka choubey

    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

  • Chinmay Kelkar

    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.

  • satish kumar

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

  • Gaurav

    nice set of questions. very helpful for those preparing for NEET. Please publish more samples.

  • Vidit panchal

    nice collection of ques….very useful..

  • Heena C. Duggal

    please explain me q.9 and i think the ans. of thirteen is pachytene.please help me to solve this.

    • Zaheer S

      Explanation of Q. No. 9
      Polytene chromosomes are over-sized chromosomes. Specialized cells undergo repeated rounds of DNA replication without cell division, forming a polytene chromosome with Chromosomal puffs which are diffused uncoiled regions of the polytene chromosome. A Balbiani ring is a large chromosomal puff.

  • gaurav

    very good for student who are going for NEET 2013. It seems that 30% questions are out side NCERT book. Will NEET exam follow same pattern, If yes whivh another nook we should follow. Thanks

  • Punit

    The ans. In Q11 should be 4th none of these because in telophase they appear again.(always may remove)

    • Punit

      In cell plate golgi vesicle and spindle microtubule make fragmoplast and after golgi vesicle release Ca & Mg who makes middle lamella.

  • komal

    can you explain me Q.4 how pattern of cleavage affet due to amount of yolk?

  • nathawani naimish

    it is a great site for solving mcq and to crack neet ug

  • ajit jagtap

    finally i got something useful on net .thanks!

  • h.farkhanda fareed

    i have match my all question thanks for do this work

  • shivani

    Cn u explain me ques. No 10 ,hw cell plate grows?

    • Rohit Gupta

      it will start growing from central part of divided cytoplasm and then grow towards cell wall..
      REF- std.xi BOO TXT. state board

  • SIMRAN

    in ques 13 , right answer is A pachytene as chiasma are formed in that phase bt they are visible during diplotene as recombination nodule starts to diappear.

    • Soumendra

      @simran…u are right but here we need to answer the way question has been asked…we can see only during the diplotene stage. during the pachytene stage chiasma formation is internal which cannot be studeid in the microscope. so ans will be diplotene only

  • Alex Monkam

    wow very helpful and easy for an exam preparation
