What will the result be if a purebred tall pea plant is mixed with a purebred short pea plant?
|
|
a short pea plant. due to chance
|
|
|
a short pea plant, because short is the dominant allele
|
|
|
a tall pea plant, because tall is the dominant allele

Explanation:
Detailed explanation-1: -A cross between a tall plant (TT) and short pea plant (tt) resulted in progeny that were all tall plants because tallness is the dominant trait. Thus, tallness is the dominant trait.
Detailed explanation-2: -In pea plants, tall plants are dominant over short plants.
Detailed explanation-3: -If we cross-bred tall (dominant) pea plant with pure-bred dwarf (recessive) pea plant, we will get plants of F1 generation. If we now self-cross the pea plant of F1 generation, we obtain pea plants of F2 generation.
