    Incomplete dominance is shown by

    A) Primrose          

    B) Mirabilis

    C) Helianthus                    

    D) China rose

    Correct Answer: B

    Solution :

    [b] Carl Correns reported incomplete dominance in Antirrhinum majus and Mirabilis jalapa. In both the cases, there are two types of flower colour in pure state, red and white. When the two types of plants are crossed, the hybrid or plants of \[{{F}_{1}}-generation\] have pink flowers.The pink colour apparently appears due to mixing of red and white colours (incomplete dominance).
