1) keep a sapling in a pot with mud. Now in this pot place a jar of water. After some days it is observed that the roots begin to grow towards the water source. This shows hydrotropism.
2) Axial position of flower and terminal position of flower.. were the two traits
3) No, eyes evolved slowly due to repeated variation caused during DNA copying leading to evolution

Take a cubical transparent glass container and fill it with water. Now put some germinating seeds in it. After one or two days you will observe that the roots of all the germinating seeds will grow towards the water. This experiment proves that roots of germinating seed show the character of positive geotropism.
(2)
The contrasting traits in relation to position of the flower of the pea plant were Axial and Terminal positions.
Axial (A) was the dominant trait and Terminal (t) was the recessive trait.
(3)
Eye is a very important and complex organ it cannot be formed by a single DNA change . First of all the rudimentary eyes of planaria and after that more and more complex eyes were produced in different organisms
