Give the pair of contrasting traits of the following characters in pea plant and mention which is dominant and recessive...

(a) yellow — dominant green — recessive (b) round — dominant wrinkled — recessive

Drwafness and wrinkled seeds are the recessive characters.

Dominant trait Recessive trait (i) The trait which appears in the F1 progeny is dominant. (ii) It appears in more numbers. (i) The trait which remains hidden or which does not appear in the F1...

(a) The dwarf traits of the plants is not expressed in the presence of the dominant tall trait. (b) In the F2 generation, both the tall and dwarf traits are present in...

(a) When Mendel cross pollinated pure tall pea plants with pure dwarf pea plants, only tall plants were obtained in F1 generation. On self pollinating the F1 progeny, both tall and dwarf...

(i) Tall (ii) 3:1 (iii) Dwarf Reason: Being a recessive trait, dwarfness can only be expressed in the absence of dominant trait/ in its pure form.

Mendel conducted a monohybrid cross with pea plants. He observed that one of the contrasting characters disappears in F1 generation. This character reappears in F2 generation (obtained by selfing F1) in...

(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)...

(i) Mendel conducted experiment on garden pea plant selecting seven visible contrasting characters. He selected and crossed homozygous tall pea plant having the genotype TT with a homozygous dwarf pea...

Mendel conducted breeding experiments on Pea plants. (i) He selected pure bred tall and dwarf plants.  (ii) He cross-pollinated these plants.  (iii) In the F1 generation, he obtained only tall plants. Tallness is...
