Question

(iv) What happens to the trait of dwarfress in pea plant
​

Answer 1

Explanation:

Since, all the plants in F1 generation have factors Tt so all of them are tall. Smallt represents recessive trait of dwarfness which is not in first generation due to presence of dominant trait T of tallness. Hence the dwarf traits are completely eliminated.

Answer 2

Answer:

Mendel in his experiment observed seven characters, tall and dwarf were one of them. Among those seven characters he observed the dominant and recessive allele, thus he found that tall was dominant over dwarf i.e. phenotype was Tall with the Tt in which T represents tall & t represents dwarf. So, the correct answer is "Recessive".
