Organophosphate resistance in the sheep blowfly (Luciliacuprina)is an example of:
A)the toxicity of insecticides.
B)the generation of neutral mutations over time.
C)a lethal frameshift mutation.
D)cumulative selection.
E)evolutionary selection of a single amino acid change in a protein.

Question

Quizplus · Accepted Answer

Organophosphate resistance in the sheep blowfly is an example of evolutionary selection of a single amino acid change in a protein. Specifically, a mutation in the acetylcholinesterase enzyme pathway results in a change in a single amino acid that allows the blowfly to break down the insecticide more effectively, leading to resistance. This is an example of adaptive evolution through natural selection.
