The graph shows the allele frequency over time for new mutations under different scenarios: (A) shows a dominant deleterious mutation decreasing in frequency over time; (B) shows a recessive beneficial mutation initially increasing slowly due to hiding from selection; (C) shows a strongly beneficial mutation rapidly increasing to fixation; (D) shows a recessive deleterious mutation decreasing to loss; (E) shows a dominant beneficial mutation increasing quickly; (F) shows an additive beneficial mutation increasing steadily due to its intermediate effect.

1. 1) The graph below shows allele frequency over time of new mutations that appear in a
population. Label each curve in the graph with the scenario that it corresponds to ( A F ) : (A)
The new mutation is dominant and is selected against. (B) The mutation is favored by selection
but is recessive. (C) The mutation is very strongly favored by selection. (D) The mutation is
recessive and s < 0 . (E) The mutation is dominant and s > 0 . (F) The mutation is co-dominant
(additive) and favored by selection.
