Select the incorrect statement for the given figure.

Options

  1. AMendel’s Law of Independent Assortment is based on the observation of dihybrid crosses (crosses between plants
  2. BThese results were not identical to those that he got when he made separate monohybrid crosses between yellow
  3. CThe yellow and green colour segregated in a 3:1 ratio.
  4. DRound and wrinkled seed shape also segregated in a 3:1 ratio.

Correct answer

B. These results were not identical to those that he got when he made separate monohybrid crosses between yellow

Step-by-step solution

When Mendel self hybridised the F 1 plants he found that 3/4 th of F 2 plants had yellow seeds and 1/4 th had green. The yellow and green colour segregated in a 3:1 ratio. Round and wrinkled seed shape also segregated in a 3:1 ratio; just like in a monohybrid cross. Based upon such observations on dihybrid crosses (crosses between plants differing in two traits) Mendel proposed a second set of generalisations that we call Mendel’s Law of Independent Assortment. The law states that ‘when two pairs of traits are comb
