Challenge Problems
Push your limits with challenges.
Question 1
You have two strains of bacteria, one unable to metabolize sugar A and the other unable to metabolize sugar B. You cross them and find the offspring can metabolize both sugars. Explain what this implies about the genes involved.
💡 Hint: Think about how metabolic pathways rely on different enzymes.
Question 2
In a lab experiment, two strains that both produce mutant phenotypes are crossed, and all offspring display the mutant phenotype. What conclusion can you draw?
💡 Hint: Consider the implications of what this means for gene function and complementation.
