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?
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?
