How did Mendel pollinate the flowers of F 1 generation.

Mendel cross-pollinated the flowers at the start of his experiment to obtain the hybrid seeds. It helped him to know the inheritance of different characteristics from parents to the offsprings. The cross-pollination was also helpful in determining the dominant and recessive characters. The character which appears in the F1 generation was considered as dominant and the other one was considered as recessive.

The cross-pollination was also helpful in determining the dominant and recessive characters. The character which appears in the F1 generation was considered as dominant and the other one was considered as recessive.

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)
