Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

In a certain plant, red flower color (R) is dominant over white (r). If a red-flowered plant is heterozygous (Rr) is crossed with a white-flowered plant (rr), what are the expected phenotypic ratios in the offspring?

💡 Hint: Construct a Punnett Square for this cross to visualize the outcomes.

Challenge 2 Hard

An individual with type AB blood has children with an individual with type O blood. What are the possible blood types of their children?

💡 Hint: Use the blood type alleles (IA, IB, i) to set up a Punnett Square.
