List two visible traits of garden pea that Mendel considered in his experiments. How do Mendel's experiments show that traits may be dominant of recessive?

Explanation

The contrasting visible characters of garden pea plant that Mendel considered were-
(1) Round and wrinkled seeds
(i) White and violet flowers
In Mendel's experiment with pea plants, when he cross-bred a tall pea plant with a short pea plant, he found that the first generation `(F_(1))` was of only tall plants. In the `F_(1)` progony, no short plants were obtained. However, in the `F_(2)` generation, both tall and short plants were obtained in the ratio 3: 1 respectively. In the `F_(2)` progeny, both traits taliness and shortness were inherited where the tall character was the dominant trait and short character was the recessive trait. In `F_(1)` generation, short trait was not able to show itself in the presence of tall trait.
