Nonsynonymous substitutions, synonymous substitutions, and pseudogenes have different rates of evolution, on average.Which order correctly represents those rates, from fastest to slowest?

Question

Quizplus · Accepted Answer

Pseudogenes evolve the fastest as they are not subject to selective pressure. Synonymous substitutions are next, as they do not change the protein and are less constrained. Nonsynonymous substitutions are the slowest due to their impact on protein function and stronger selective pressure.
