Text Solution
Verified by ExpertsThe correct answer is:
Let's use Mendel's cross of tall and dwarf pea plants as an example.
The 
plants of genotype Tt are self-pollinated. Both tall (T) but with dwarf (t) alleles).
Phenotypic ratio : Tall ： Dwart
Genotypic ratio : Pure tall : Hybrid : Pure dwarf
Thus, the tall parents plants having heterozygous alleles, results in offsprings which comprises of both tall and dwarf plants.
