Question

how Mendel proved that tallness is the dominant trait and dwarfness is recessing in a pea plant? explain with the help of an monohybrid cross

Answer 1

this is the answer.
hope this helps .

Answer 2

Mendel's experiment

Explanation:

Mendel found that when a feature or characteristic is observable, it is the dominant trait and the other contrasting trait is recessing. So in order to prove this, he considered a pea plant which was breeding tall (TT) and dwarf (tt). He crossed these two plants. The seeds formed after fertilizing the tall and dwarf pea plants were grown. These new plants represent the first filial or F1 generation. He observed that all the F1 plants were tall.

Mendel then self-pollinated the F1 plants and observed that all plants obtained in the F2 generation were not tall. He observed that one-fourth of the F2 plants were short.

From this experiment, Mendel concluded that the F1 tall plants were not true breeding. They were carrying traits of both tall and dwarf plants. They appeared tall only because the tall trait was dominant over the dwarf trait.
