What makes a trait useful for inclusion in phylogenetic analysis?
Homework Answers
Answer- A trait is useful for phylogenetic analysis when it is heritable, means it is get transferred from parents to offsprings and shows some changes in different groups of organisms. Such type of trait must be present in encestor in simple from and shows various levels of divergence in various descents.

10. Which of the following statements describes a purpose for which biologists use phylogenetic trees? a. For human diseases once found only in other animals, phylogenetic trees are helpful in determining when and where the infectious organisms first entered human populations. b. Phylogenetic trees are useful for determining how many times a particular trait may have evolved independently within a lineage. c. Phylogenetic trees can be used to reconstruct ancestral traits. d. Phylogenetic trees can be used in conjunction with...

During phylogenetic analysis, what is the purpose of using the bootstrapping method? To determine the best nucleotide substitution model. To assess the accuracy of the multiple sequence alignment. To calculate the probability of selecting an appropriate outgroup. To assess the accuracy of a particular tree topology. Which of the following phylogenetic methods calculates posterior probabilities to identify the tree that has the maximum probability? Bayesian inference. Maximum likelihood. Maximum parsimony. Genetic distance inference.

Analysis based on two individual genes (gene trees) may imply two different phylogenetic relationships among a group of species. List three possible reasons for this (1), and explain how one of them works (2). If only one phylogenetic tree accurately represents the true evolutionary history of these species, what might we do in order to determine which one is correct (2)?
