    Gynandromorphs develop in Drosophila when the two cells in the two-celled proembryo will have one of the following chromosomal sets [MP PMT 1997]

    A) 2A + XX in one cell and 2A + X in the other

    B) 2A + X in both the cells

    C) 2A + XXX in both the cells

    D) All of the above

    Correct Answer: A

    Solution :

    Gynandromorphs are formed due to misdivision of chromosomes and start as female with 2A + 2X chromosomes. One of the x-chromosomes is lost during the division of the cell with the result that one of the daughter cells possesses 2A + 2X chromosomes and the other 2A + X.
