  • In a Mendelian experiment, breeding of tall pea plants (TT) bearing violet flowers (WW) was done with short pea piants (tt) bearing white flowers (ww). The progeny all bore violet flowers, but almost half of them were short. The genetic make-up of the tall parent can be 1. TTWW 2. TTWW 3. TUWW 4. TUWW Which of these make-ups is/are correct ?

    A
    1 and 2 only
    B
    2 and 3 only

    3 only

  • Assertion: A geneticist crossed a pea plant having violet flowers with a pea plant with white flowers, he got all violet flowers in first generation. Reason: White colour gene is not passed on to next generation.

    A
    Both A and R are true, and R is correct explanation of the assertion.
    B
    Both A and R are true, but R is not the correct explanation of the assertion.
    C
    A is true, but R is false.
    D
    A is false, but R is true.

    (a) A garden pea plant bearing terminal, violet flowers, when crossed with another pea plant bearing axial, violet flowers, produced axial, violet flowers and axial, white flowers in the ratio of 3 : 1. Work out the cross showing the genotypes of the parent pea plants and their progeny. (b) Name and state the law that can be derived from this cross and not from a monohybrid cross.

    Name the type of cross that would help to find the genotype of a pea plant bearing violet flowers.

    A tall pea plants bearing violet flowers is given with its unknown genotypes. Explain by working out the crosses how would you find the correct genotypes with respect to the two traits mentioned only by " selfing" the given plants.

    Tall pea plant with red flower crossed to dwarf with white flower yields only tall red plants. A test cross shall give a ratio of:

    A breeder crossed a pure breed tall plant having white flowers tall pure short plant having blue flowers. He obtained 202 F_(1) progeny and found and found that they are all tall having white flowers. Upon selfing these these F_(1) Plants, he obtained a progeny of 2160 plants. Approximately, how many of these are likely to be short and having blue flower?
