Question 1

What does a complementation test reveal?

  • It shows if mutations are in the same gene.
  • It shows if mutations are in different genes.
  • It calculates crossover frequency.

💡 Hint: Think about repairing a broken gene!

Question 2

True or False: All genes are defined strictly by their coding regions.

  • True
  • False

💡 Hint: Consider what controls the timing and amount of expression!

Challenge Problems

Push your limits with challenges.

Question 1

In a study, two mutant strains of bacteria are analyzed. One strain (A) has a mutation that prevents it from synthesizing nutrient X, while the other strain (B) has a mutation preventing the production of nutrient Y. If a cross between them produces offspring that can grow on both nutrients, what can you conclude about the mutations?

💡 Hint: What does this imply about the function of those genes?

Question 2

Two genes, A and B, are linked on the same chromosome. If 40 out of 1000 offspring from a dihybrid cross are recombinant, calculate the recombination frequency and interpret what it indicates about the genetic distance between the two genes.

💡 Hint: What does this frequency tell you about their arrangement?
