Question

explain mendel's experiment with Peas on Inheritance of traits considering to visible contrasting characters

Answer 1

Mendel selected garden pea for his breeding experiment because of its contrasting characters such as height of the plant, yellow or green seed, round or wrinkled seed shape. Mendel hybridized or cross-pollinated plants with alternate forms of a trait. He crossed tall and short plant to obtained F1 progeny. In F1 generation all plants were tall. Then he allowed the hybrid plants of F1 generation to self-pollinated. In F2 generation all the progeny were tall as well as short plants. This results that the three quarter plants were tall and one quarter was short.

Answer 2

Mendel’s experiment can be studied in the following ways:

(i) Mendel first crossed pure-bred tall pea plants with pure-bred short pea plants and found that tall pea plants were produced in the F1 generation.

(ii) Mendel crossed the tall pea plants of the F1 generation and found that tall plants and dwarf plants are in the ratio 3:1. Mendel observed that the dwarf trait of the pea plant which had disappeared in the F1 generation progeny reappeared in the F2 generation. He concluded by saying that traits are inherited independently.
