Questions and Answers
  • 1. 
    Which of the following is not a source of genetic variation in sexually-reproducing organisms which undergo meiosis?
    • A. 

      Crossing over

    • B. 

      Independent randomization of chromosome orientation

    • C. 

      Random fertilisation

    • D. 

      All of the above

    • E. 

      None of the above

  • 2. 
    Two cells have n sets of duplicated chromosomes attached at their centromeres, which are not genetically identical to the chromosomes of their parent cells nor to each other. The centrosomes are migrating towards opposite poles of the cell. The duplicated chromosomes have not aligned yet. This stage of meiosis is [Blank].
  • 3.

    • A. 

      Interphase

    • B. 

      Prophase I
