When Mendel crossed a pure tall plant with a dwarf one he got only tall plants in F1 generation. When these F1 generation were self pollinated Mendel got tall and dwarf in the ratio 3:1. The character which was expressed in the first gen is dominant. The one which was not expressed in the F1 grand later reappeared in F2 gen is recessive.

Mendel crossed two pea plants one with tall trait (TT) and another with short trait (tt). The tall trait was dominant and the short trait was recessive. When these two plants were crossed then offspring were all tall in nature. But when the F1 Generation were intercrossed then all plants 75% of pea plants were tall and 25% were short. In this way Mendel explained that traits may be dominant or recessive.
