    One chromosome of a homologous pair carries the genes J and K. The other chromosome of the pair carries the genes j and k at corresponding loci. Crossing over results in exchange of chromosome segments and production of gametes with new combinations of genes. A recombinant type gamete resulting from this crossover might contain:  

    A) Genes J and K  

    B)                    Genes j and K

    C) Genes J and j   

    D)                    Genes j and k

    Correct Answer: B

    Solution :

    [b] Crossing over does not alter the traits that are coded for it only affects the variant that is coded for.
