Question

(i) Why did Nlendel choose garden pea for his experiments? Write two reasons.
(ii) List two contrasting visitrle characters of garden pea Mendel used for his experiments.
(iii) Explain in brief how Mendel interpreted his results to show that the traits may be dominant or recessive.

Answer 1

(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.
