The Same Intron Was Sequenced from Five Different Taxa (Taxa

question 109

Multiple Choice

The same intron was sequenced from five different taxa (taxa A-E) whose evolutionary relationships are disputed. The data matrix given shows six variable sites (1-6, left column) in the DNA sequences obtained from each of the five species. Taxon A serves as the outgroup for this analysis. $\begin{array}{|c|c|c|c|c|c|}\hline & \operatorname{taxon} \mathrm{A} & \operatorname{tax} n \mathrm{~B} & \operatorname{tax} n \mathrm{C} & \operatorname{taxon} \mathrm{D} & \operatorname{taxon} \mathrm{E} \\\hline 1 & \mathrm{~A} & \mathrm{G} & \mathrm{G} & \mathrm{G} & \mathrm{G} \\\hline 2 & \mathrm{C} & \mathrm{T} & \mathrm{T} & \mathrm{T} & \mathrm{T} \\\hline 3 & \mathrm{G} & \mathrm{G} & \mathrm{G} & \mathrm{G} & \mathrm{A} \\\hline 4 & \mathrm{~A} & \mathrm{~A} & \mathrm{~T} & \mathrm{~A} & \mathrm{~T} \\\hline 5 & \mathrm{~A} & \mathrm{C} & \mathrm{A} & \mathrm{C} & \mathrm{C} \\\hline 6 & \mathrm{~A} & \mathrm{~A} & \mathrm{C} & \mathrm{A} & \mathrm{C} \\\hline\end{array}$ Which of the phylogenies below explains the relatedness between these taxa with the FEWEST evolutionary steps?

• A)phylogeny I
• B)phylogeny II
• C)Both phylogenetic trees have the same number of evolutionary steps.
