The hybridization process of a tall round seeded plant with a dwarf wrinkled seeded plant is illustrated below What may be the characters that will appear in the plants produced as a result of the self pollination of the first generation?

Mendel chose only seven contrasting characters for his experiments. In each contrasting character, one trait was dominant, and the other trait was recessive. In the given illustration the hybridization process of a tall round seeded plant with a dwarf wrinkled seeded plant is depicted. In the given diagram (i) will be TR and (ii) will tr. The T and R represent the dominant trait while t and r represent the recessive trait. These traits determine the phenotype of the organisms. The F2 generation will be TtRr x TtRr The result of the self-pollination of the first generation can be depicted below: Gametes TtRr → TtRr TR Tr tR tr TR TTRR (tall plant, round seed) TTRr (tall plant, round seed) TtRR (tall plant, round seed) TtRr (tall plant, round seed) Tr TTRr (tall plant, round seed) TTrr (tall plant, wrinkled seed) TtRr (tall plant, round seed) Ttrr (tall plant, wrinkled seed) tR TtRR (tall plant, round seed) TtRr (tall plant, round seed) ttRR (dwarf plant, round seed) ttRr (dwarf plant, round seed) tr TtRr (tall plant, round seed) Ttrr (tall plant, wrinkled seed) ttRr (dwarf plant, round seed) ttrr (dwarf plant, wrinkled seed) The result will be: Tall plants with round seeds (TTRR, TTRr, TtRR, TtRr) . Tall plants with wrinkled seeds (TTrr, Ttrr). Dwarf plants with round seeds (ttRR, ttRr). Dwarf plants with wrinkled seeds (ttrr)

Observe the hybridization experiment given below. Illustrate this hybridization experiment using symbols.

When plants that differ in a pair of contrasting traits are hybridized, only one trait is expressed while the other remains hidden in the offsprings. The expressed trait is called the dominant trait and the hidden trait is called the recessive trait.

Observe the hybridization experiment given below. Illustrate the second generation formed by the self-pollination of first-generation plants.

When the F1 generation's plant self-pollinated, most of the plants in the F2 generation has green coloured seeds as green colour is dominant over yellow coloured. The ratio of the result obtained is approximately 3:1. It means out of four plants three are with green seed and one is with yellow seed.
