(a) Why did Mendel choose garden pea for his experiments ? Write two reasons. (b) List two contrasting visible characters of garden pea Mendel used for his experiment. (c) Explain in brief how Mendel interpreted his results to show that the traits may be dominant or recessive.
Answers
Answer:
Mendel choose garden pea for his experiment because of the following reasons: ... It is easy to cross-pollinate the plant because pollen from one plant can be introduced to the stigma of another plant by removing of anthers.
Mendel demonstrated that traits can be either dominant or recessive through his monohybrid cross. He crossed true-breeding tall (TT) and dwarf (tt) pea plants. ... They appeared tall only because the tall trait was dominant over the dwarf trait. This shows that traits may be dominant or recessive.
Answer:
(i) Mendel choose garden pea for his experiments because : (a) Pea plant is small and easy to grow (b) A large number of true breeding varieties of pea plant are available. (c) Short life cycle. (d) Both self and cross pollination can be made possible. (Any two) (ii) Contrasting characters : (a) Round/ Wrinkled seeds (b) Tall/ Short plants (iii) When Mendel crossed two pea plants with a pair of contrasting characters only one character appeared in all the members of F1 progeny, the other remains hidden. On selfing F1, the hidden characters reappeared in just 25% of the offsprings and the other 75% shared the characters expressed in F1. Mendel concluded that the character which expresses itself in F1 and in 75% of the individuals of F2 is dominating while the other is recessive.
