Identify the Mutation Types

Three aligned sequences with three mismatches.

The image shows the same three aligned from the preious two slides. They are: A C A G A C dash G A, A C A T A C A G A, and A C dash T A C dash G A. Again, three boxes surround the positions where nucleotides are mismatched.

Now that we can see what changes there have been in DNA sequences, how can we figure out which sequences are more closely related?
