.1. Phylogenetic tree: Change in characteristics occurs in lineages over time. Rate of mutation is not constant over time and for all lineages in phylogenetic tree. So, leaves can have different distance from the root. As, we have no idea how these rabbits are related in evolution. Construct a phylogenetic tree from table below using Neighbor Joining Method.

Please associate the explanation with the correct de-extinction methods, some of which are still only possible in theory. Genes from extinct species are cut and pasted into the genome of a relative species using the molecular tool CRISPR. Relatives of the extinct species are hybridized or selected of specific traits with the goal of creating morphologically similar species that can perform the same ecological function as the extinct relative. The nucleus of an intact cell from an extinct species is inserted into the egg of a living relative. 1. Back-breeding 2. Cloning 3. Genomic reconstruction
Where in a phylogenetic tree would you expect to find the organism that had evolved most recently? at the base within the branches at the nodes at the branch tips
In a cladistic analysis, a systematist groups together organisms that share: derived homologous traits. derived homoplastic traits. ancestral homologous traits. ancestral homoplastic traits. all of the above.
To construct a phylogenetic tree by applying the principles of parsimony to molecular sequence data, one would: a. start by making assumptions about variations in the rates atwhich different DNA segments evolve. b. group together organisms that share the largest number ofancestral sequences. c. group together organisms that share derived sequences, matching the groups to those defined by morphologicalcharacters. d. group together organisms that share derived sequences, minimizing the number of hypothesized evolutionarychanges. e. identify derived sequences by studying the embryology of theorganisms.
Phylogenetic trees are a type of model that can be used to show how organisms are related through common ancestry. The phylogenetic tree model represents nodes numbered 1 through 8. Using evidence from the phylogenetic tree determine which species would be MOST closely related to the species on branch C? Question options: The species on Branch A is most closely related to the species on branch C because they share the most recent common ancestor at node 1. The species on Branch B is most closely related to the species on branch C because they share the greatest number of common +ancestors. The species on Branch A & B are both most closely related to the species on branch C because they share the most most recent common ancestor at node 2. The species on Branches F, G, H, and I are all equally related to the species on branch C because they all split from a common ancestor at the same time which is illustrated by having nodes 2 and 7 at the…
(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)?
Do you find it easy to interpret phylogenetic trees? What aspects are the most challenging or what aspects of the tree can be easily misinterpreted? What strategies can students use to correct or avoid these common misinterpretations? Do you consider phylogenetic trees to be reliable indicators of evolutionary relationships? Include a reference.
Follow up on Question 2. The purpose of including species D in the phylogenetic reconstruction is so that it can be used as a. an in-group for inferring the polarity of trait evolution b. an out-group for inferring the polarity of trait evolution c. an ancestral group for inferring the polarity of trait evolution d. a monophyletic group for classifying vge gene types e. None of the above
100. Maximum parsimony (i.e., Occam's razor) is used for many things, including the construction of phylogenetic trees. It can best be described as _________. A. intermediate models are best because they're not too simple, not too complex B. the simplest explanation is usually the correct one C. the most complex one is best because nature is complex D. none of the above – models should be chosen on a case-specific basis
Phylogenetic trees are diagrams used to reflect evolutionary relationships among organisms or groups of organisms. _______ trees have a single ancestral line to which all organisms in the diagram relate to. ______ do not have a common ancestor but do show relationships among species.
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.
Molecular marker is used to determine relatedness of species which may directly or indirectly exerts an effect on diversity. A hypothetical ancestor has the following DNA sequences: G A A G C T A T T C A T T. There are two lineage with DNA sequences of G A A G G T A T T C T C G, and G A A C C T A T T C T G C. (1) Determine the percentage of A and T in the DNA sequence of the hypothetical ancestor. (2) Calculate the percentage of each nitrogenous base in the second lineage.
