Challenge Problems
Push your limits with advanced challenges
If a red-flowered snapdragon (RR) is crossed with a white-flowered one (rr), how many distinct phenotypes can you anticipate in the F2 generation?
💡 Hint: Remember to think about how self-crossing works.
Given that pink flowers are created from a red and white snapdragon, predict the genotypes and phenotypes if pink flowers are crossed in the F2 generation.
💡 Hint: Consider potential combinations in the offspring.
