NEET Biology NEET PYQ-Cell Cycle And Cell Division

  • question_answer
    The formation of multivalents at meiosis in diploid organism is due to: [AIPMT 1998]

    A) monosomy

    B) inversion

    C) deletion

    D)   reciprocal translocation

    Correct Answer: D

    Solution :

    [D] In case a translocation is present in one of the two sets of chromosomes, this will be translocation heterozygote. In such an organism, normal pairing into bivalents would not be possible. Instead, pairing between homologous segments of chromosome would result in an 'X' shaped arrangement involving four chromosomes (multivalent).
