Explanation

In Mendel's pea plant experiments,

When he crossed purebred pea plants with contrasting traits (like purple and white flowers),

The F1 generation offspring all exhibited the dominant trait (purple flowers in this case).

The recessive trait (white flowers) disappeared in the F1 generation but reappeared in the F2 generation when the F1 plants self-fertilized. T

his reappearance of the recessive trait in the F2 generation confirmed that the recessive allele was still present in the F1 generation, just masked by the dominant allele.
