Which of the following statements about the round-seeded pea plants obtained in the F₂ generation is FALSE?

Quizplus · Accepted Answer

In the F1 generation, all the plants were hybrid for seed shape. When these plants self-fertilized, the expected genotype ratio in the F2 generation is 1:2:1 (one homozygous dominant, two heterozygous, and one homozygous recessive). Therefore, we expect 25% of the round-seeded plants in the F2 generation to be homozygous for the dominant round-seed allele. Therefore, option C is false. Options A, B, and D are true based on Mendel's law of segregation and law of independent assortment.
