which of the following double mutants could show synthetic genetic enhancement? select all that apply. A) Two null mutants (A, B) in genes with redundant function (A -> C, B -> C). B) Two hypomorphic mutants (A, B) in the same linear pathway (A -> B -> C). C) A constitutively-active mutant (A) and a null mutant (B) in genes with redundant function (A -> C, B -> C). D) Two null mutants (in A and B) in the same linear pathway (A -> B -> C)

Answer

The following double mutants could show synthetic genetic enhancement: A) Two null mutants (A, B) in genes with redundant function (A -> C, B -> C). B) Two hypomorphic mutants (A, B) in the same linear pathway (A -> B -> C).

Q: What is synthetic genetic enhancement? A: Synthetic genetic enhancement refers to the phenomenon where the phenotype of the double mutant is better than the additive phenotype of the single mutants.
Q: Which of the following double mutants fit the criteria for synthetic genetic enhancement? A: The following double mutants could show synthetic genetic enhancement: A) Two null mutants (A, B) in genes with redundant function (A -> C, B -> C). B) Two hypomorphic mutants (A, B) in the same linear pathway (A -> B -> C).
Q: Do any of the other options fit the criteria for synthetic genetic enhancement? A: C) A constitutively-active mutant (A) and a null mutant (B) in genes with redundant function (A -> C, B -> C) and D) Two null mutants (in A and B) in the same linear pathway (A -> B -> C) do not fit the criteria for synthetic genetic enhancement.
