As per Mendel's experiment on monohybrid cross, a cross is performed between a heterozygous tall (Tt) and a homozygous dwarf (tt) garden pea plant. What would be the percentage of tall pea plants in the filial (F?) generation?
A) 25%
B) 50%
C) 75%
D) 100%
Dear student,
The question seem to have certain typing errors but making certain assumptions, kindly find your answer bellow:
The correct answer is (B) 50%
Explanation: In a cross between homozygous recessive (tt) and heterozygous tall (Tt), the gametes formed by respective parents are:
Homozygous recessive (tt)- t
Heterozygous tall (Tt)- T, t
by using punnette square method the possible combinations in offsprings are:
So, 2 types of offsprings, heterozygous tall and homozygous recessive will be produced in 1:1 genotypic and phenotypic ratio. Thus 50% is the answer.
Regards,

| t | tt |
So, 2 types of offsprings, heterozygous tall and homozygous recessive will be produced in 1:1 genotypic and phenotypic ratio. Thus 50% is the answer.
