Question

Which of the following is totally impossible outcome of Mendel�s Experiment?

        a. 3 tall 1 short plant

        b. 24 tall and 8 short plants

        c. 8 tall and 0 short plants

        d. 4 tall plants and 1 medium height plant.

​

Answer 1

Answer:

 d. 4 tall plants and 1 medium height plant.

MENDEL'S EXPERIMENTS

Also, 1/4 of the F2 (2nd generation) plants in Mendel's experiments bred true as tall plants and 1/4 bred true as short plants. The same pattern occurred for the other traits Mendel measured. For example, parent plants produced only smooth (S) or wrinkled (s) seeds when self-pollinated.

Answer 2

Option D is correct

4 tall plants and 1 medium height plant.

Explanation:

• In an F1 cross, one pure short and tall pea plants were crossed and the result was heterozygous tall so option C is incorrect.
• In the cross of selling 3:1 is generated, thus option A and B are impossible.
• D is not possible because either short or tall plants are produced and there are no medium plants
