Challenge Problems

Push your limits with challenges.

Question 1

Consider a plant species where red flowers (RR) and blue flowers (BB) show incomplete dominance producing violet flowers (RB). If two violet plants are crossed, what are the expected offspring ratios for red, violet, and blue flowers?

💡 Hint: Construct a Punnett square to visualize the combinations.

Question 2

A certain species of fish has incomplete dominance for fin color where red (RR) and white (rr) combine to form pink (Rr). If a pink fish breeds with a red fish, what percentage of the offspring would you expect to be pink?

💡 Hint: Use the Punnett square method to calculate the outcome.
