Why was the idea of blending of traits not supported by Mendel's experiments?

Answer and explanation

Correct answer: Because the hidden trait appeared again in the second generation

The blending theory predicted that two parental traits would permanently mix, so a hidden trait should not reappear unchanged. Mendel crossed pea plants with contrasting traits and observed that the recessive dwarf trait disappeared in the F1 generation but reappeared in the F2 generation. This showed that hereditary factors remain discrete and are passed on separately. Therefore, option A is correct; B, C, and D contradict the actual observations.
