Comparing the 4 phylogenetic trees above, three of the four trees show the exact same relationship between species A, B, and C Which tree shows a different relationship? 3. Based on the 4 phylogenetic trees above, homologous DNA sequences from species A and B are expected to be more similar to one another than those of species B and C. a. True b. False The following phylogenetic tree will beExplanation / Answer
Answer 2. tree number 2 shows a different relationship
Answer 3. FALSE. as species B and C are more closely related therefore homologous squences from these will be more similar than A and B
Answer 4. common ancestor of B and C lived more recently.
Answer 5. a. from root to branch tip.
Answer 6. c. Both of the above
Answer 7. a. they are a way to visualize how different species are related.
