1. The images below is DNA sequence (in reading frame) and the amino acid translation for homologous
regions of a protein coding gene for two species you are researching. 5139619szbe Gdilii-‘k * iii! *iil‘l‘ iir‘kiiii *** I'liiir *iii iv iiiliii’iiiilit- ii I *irzlri‘il‘ i: *iii‘i ****l 1. Pan troglodytes IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII

Place either an “N” or an “S” in the space above
the mutation in the DNA alignment. b. How many non-synonymous mutations (N) are
there? c. How many synonymous mutations (S) are there? (1. What is the was? How is this different than the 3:1st ratio? e. If the value fiom part (1. above was an mm ratio, would you estimate the gene had been under
selection in these lineages or has it been evolving neutrally? If it is under selection, what type of
selection pressure is at work?
