  3. (c) The genetic make-up of the tall parent can be depicted as TtWW Since all the progeny bore violet flowers, it means that the tall plant having violet flowers has WW genotype for violet flower colour. Since the progeny is both tall and short, the parent plant was not a pure tall plant. Its genotypRead more

    (c) The genetic make-up of the tall parent can be depicted as TtWW
    Since all the progeny bore violet flowers, it means that the tall plant having violet flowers
    has WW genotype for violet flower colour.
    Since the progeny is both tall and short, the parent plant was not a pure tall plant. Its
    genotype must be Tt.
    Therefore, the cross involved in the given question is
    TtWw × ttww

    TtWw − ttww
    Therefore, half the progeny is tall, but all of them have violet flowers.
