How did Mendel interpret his result to show that traits may be dominant or recessive? Describe briefly. (Delhi 2016)

  Mendel crossed the pea plant for two contrasting characters under consideration.  The feature that showed in the F₁ generation was dominant, whereas the one that did not was recessive. Later, he selfed the F₁ generation plants and recovered, resulting in the F₂ generation having a clear proportion of both parental features. Mendel determined from his findings that the characteristic was dominant when it showed itself in the F₁ generation and recessive when it did so in the F₂ generation.

It can be demonstrated by the following cross:
