In a monohybrid cross between two heterozygous (Tt) tall pea plants, what is the expected genotypic ratio of the offspring?
Show answer and explanation
Correct answer: 1:2:1
While the phenotypic ratio is 3:1 (Tall:Dwarf), the genotypic ratio is 1:2:1. This represents 1 homozygous dominant (TT), 2 heterozygous (Tt), and 1 homozygous recessive (tt) plant.
