A true breeding plant is

In one of his experiments with pea plants Mendel observed that when a pure tall pea plant is crossed with a pure dwarf pea plant, in the first generation, F_(1) only tall plants appeared. (i) What happens to the traits of the dwarf plants in this case? (ii) When the F_(1) generation plants were self-fertilised, he observed that in the plants of second generation, F_(2) both tall plants and dwarf plants were present. Why it happened? Explain briefly.

A pea plant with blue colour flower denoted by BB is cross-bred with a pea plant with white flower denoted by WW. (i) What is the expected colour of the flowers in their F_(1) progeny? (ii) What will be the percentage of plants bearing white flower in F_(2) generation, when the flowers of F_(1) plants were selfed? (iii) State the expected ratio of the genotype BB and BW in the F_(2) progeny.
