What is the expected phenotypic ratio of tall to dwarf offspring in a monohybrid cross Tt x Tt?
💡 Hint: Remember the classic Mendelian ratios when two heterozygotes are crossed.
True or False: All traits are expressed equally in heterozygous conditions.
💡 Hint: Consider the definition of dominance.

Challenge Problems
Push your limits with advanced challenges
A plant is heterozygous for height (Tt). If self-pollinated, calculate the expected phenotypic ratio and explain the genetic outcomes.
💡 Hint: Utilize a Punnett square for accurate predictions.
In a pea plant experiment, if the dominant trait for smooth seeds (S) is linked with the recessive trait for yellow seeds (s), propose a breeding scheme to prove dominance. What are your expected ratios?
💡 Hint: Again, a Punnett square will visualize all potential crosses effectively.
