Question

The genomes of three species of mouse are being sequenced, and a particular DNA sequence found in all three species is found to have a steady mutation rate. The sequence of interest for these three species is shown below.

Species A: ATTCGGATTATTCGAGG
Species B: GTCCGGTTCATTGGACA
Species C: ATCCAGATCGTTCGTGG

Which of the following inferences can be made, based on this information?

Answer 1

Species B and Species C most likely diverged from Species A since they both have more mutations than Species A.

Species B most likely evolved from Species C since they are closest to each other in terms of number of mutations.

Species A and Species C most likely share the most recent common ancestor since they differ by the fewest mutations.

Species C most likely diverged from Species A more recently than Species B since Species C has fewer mutations than Species B.

Answer 2

what lesson and unit is this from? I seen it somewhere.
