|
|
Tt
|
|
|
TT
|
|
|
tall
|
|
|
short
|
Explanation:
Detailed explanation-1: -As the given genotype is Tt, it’s a heterozygous condition and in heterozygous condition the dominant trait (T-tall) will express itself. Hence, the phenotype of Tt will be a tall plant. Q.
Detailed explanation-2: -Answer and Explanation: A tall pea plant with (TT) and a tall pea plant with (Tt) have the same phenotype but different genotypes. Phenotype is the appearance (trait), both plants appear tall.
Detailed explanation-3: -An organism can be either homozygous dominant ( TT ) or homozygous recessive ( tt ). If an organism has two different alleles ( Tt ) for a certain gene, it is known as heterozygous (hetero-means different). Phenotype is a way to describe the traits you can see.
