Shown above are three possible phylogenetic trees for species I, II and III reconstructed based on the 4-nucleotide DNA sequences given in the righthand table. In every tree, each hatchmark on a branch represents a single base-change event. The most parsimonious tree would be - A. Both X and Y. B. X. C. Y. D. Both Y and Z. E. Z.
Referring to the phylogenetic tree shown above, answer the following questions: 1. How many OTUs are included in the phylogenetic analysis? 2. How many clades are there? 3. What is an autapomorphic trait of the domestic cat? Explain why? 4. What is the shared derived trait (synapomorphy) in the Family Felidae? Explain why?
Count the instances where there is any difference in the amino acid in the alignment of the six sequences and write that number below. Did you find any clades in this alignment? Describe your results. You must describe in detail the relationships between the sequences in this tree. Describe in detail how this combined tree changed the relationships between the sequences in comparison to the two separate trees that you created in the previous section above
Suppose a new monkey species, Species A, has just been discovered. You are a primatologist, and you are trying to determine its phylogenetic position. You are sure its closest relatives are Species B and Species C, but you want to know which one it is more closely related to or if it is equally closely related to both. You are using Species D, a more distant relative, as the outgroup. You have come up with a list of ten characters you think will be useful in resolving this phylogeny, and you have determined the character state of each species for each character. The character states are: (in image below) Estimate the phylogeny of these taxa by plotting the changes on each of the three possible phylogenies for species A, B, and C and determining which tree requires the fewest evolutionary changes. HINT: First, review the carnivorans problem in Section 4.3 of the Zimmer and Emlen textbook. To solve the above problem, assume the outgroup has the ancestral character state for each…
I was given this and made a character matrix from it but I need help creating the most parsimonious phylogenetic tree for it.
(top or bottom) Species A, B, C, D, and, E are all extant species (living today; not to be confused with “extinct” species). Consider the common ancestor shared between humans and species A (ancestor A-H), the common ancestor between species B and humans (ancestor B-H), etc. Which of thetwo trees below best represents the phylogenetic relationship between species shown in the nucleotide divergence plot above (top tree or bottom tree)?
There are 27 sequences from 27 individuals belonging to an unidentified group of organisms. Eleven (11) sequences were mined from NCBI while the rest are unpublished sequences from Mindanao. Sequences labeled with "SSL" are from Agusan Marsh while sequences labeled with "CKL/CITLR" and "CWL" are from Camiguin Island and Dinagat Islands respectively. Finally, sequences labeled with "MSLA" are from Mt. Magdiwata. From the nucleotide results and generated phylogenetic tree below: a) What group of organisms is represented by the phylogenetic tree? b) Identify the source (species) of each sequence. c) How many species are present in the generated tree? d) What species is considered as the outgroup? e) What genetic marker is utilized to generate the sequences? f) Which specimen group is more closely related to "SSL"? CKL or MSLA? Justify your answer h) Based on the results, what possible species name can be assigned to the MSLA group?
Below is an example of a particular kind of phylogenetic tree called a chronogram. Chronoograms are named because the length of the branches represents different lengths of time. Nodes are represented by vertical lines, and branches with horizontal ones. They can be arranged horizontally, with the most recent evolutions on the right. Given this information, the taxa that is most closely related to Dubautia ciliolata c. 529 (highlighted below) is _________________ (make sure to type exactly the same characters, including the numbers; do not italicize).
Please help with the following: ______________ can be used to determine the last common ancestor shared by two divergent species. A. Y-chromosome analysis B. VNTR analysis C. Rudolph's admixture hypothesis D. mtDNA analysis E. whole DNA sequencing

Which of the following best explains why coalescent-based phylogenetic inference is important in the age of phylogenomics? A) Coalescent-based methods directly model gene tree histories independently to infer the species tree in a summary-based manner, which is important for phylogenomic analysis were hundreds to thousands of gene histories are analyzed. B) Coalescent-based methods have the most advanced evolutionary models of molecular evolution, which is important for phylogenomic analysis were hundreds to thousands of gene histories are analyzed. C) Coalescent-based methods are no more important than other types of phylogenetic inference, even for phylogenomic analyses. D) None of the above.
Which of the following statements best explains the importance of sister taxa for understanding the evolution of ingroup taxa? A) The sister group informs of the likely state of the common ancestor of the ingroup. B) The sister group is composed only of ancestral characters representing a primitive taxon having ancestral states for all characters able to be studied. C) The sister group allows us to infer character state polarity in order to understand how character states have changed during evolution of the ingroup. D) A & B E) A& C F) All of the above.
