Below is an aligned DNA sequence dataset for three species and their outgroup.
1. Draw the maximum parsimony tree for this dataset with all nucleotide changes
mapped onto it. Assume Z is an outgroup.
2. Map any homoplasies as reversals, and mark them with asterisks.
3. Make a list of the characters that show autapomorphies below the chart.
