Choose all that apply: Which of the following are methods of detecting that there has been selection for a particular allele? a. There is a higher number of nonsynonymous mutations compared to synonymous mutations in the sequence of interest. b. Changes in the DNA sequence occur in accordance to expectations from the molecular clock. c. A selective sweep occurred. Neutral variation that is nearby an allele that is under strong positive selection is eliminated. d. The proportion of synonymous changes...
