Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

You're studying a population of pea plants where tallness (T) is dominant over shortness (t). If two heterozygous plants are crossed, what are the possible genotypes and phenotypes of the offspring?

💡 Hint: Set up a Punnett square to visualize your results.

Challenge 2 Hard

In a family, the trait for brown eyes (B) is dominant over blue eyes (b). If one parent has brown eyes and is heterozygous and the other has blue eyes, determine the potential phenotypic ratio of their children.

💡 Hint: Sketch a Punnett square for clarity.
