Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

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.

Challenge 2 Hard

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.
