    Lack of independent assortment of two genes A and B in fruit fly Drosophila is due to:

    A) repulsion            

    B) recombination 

    C)  linkage                                

    D)  crossing over

    Correct Answer: C

    Solution :

    W. Bateson (1905) explained the lack of independent assortment in sweet pea and T.H. Morgan (1910) in Drosophila due to linkage. When genes closely present adhere or link together in a group and transmitted as a single unit, the phenomenon is called, linkage. It stops the process of independent assortment. Incomplete linkage is broken down due to the crossing over.
