- Examine the following phylogenetic tree illustrated in Figure shown in the first picture. In general, what does a phylogenetic tree illustrate? How do you compare the relationships of organisms BB, CC, and DD? Given the following organisms in the Table in the second picture, number them in terms of which is relatively closest and distant. Number 1 refers to closest.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…Draw a simple phylogenetic tree for two sisters clades with a common ancestor. Each sister clade consists of two taxa. Define the following terms and use to label your diagram: clade, node, branch, common ancestor, and taxon.
- For the first phylogenetic tree, if we assume absolute time is NOT represented, can we say that the species in circle B are more closely related than the species in Circle A? For the second phylogenetic tree (if we hold the same assumptions), can we say that B and C are more closely related than A and C?In the table below is a short gene sequence in 4 closely related taxa and an outgroup. Based on comparisons of this DNA sequence, determine the placement of these four taxa in the phylogenetic tree below. Clearly identify the taxon (P, Q, R, or S) that corresponds to each branch tip (1, 2, 3, or 4). Based on your constructed tree, is Species P more closely related to Species Q or Species S? Justify your answer.Currently, two of the extant porpoise species (Y and Z) are placed in the genus Tursiops, and a third species (X) is placed in the genus Delphinus. Assuming this classification reflects evolutionary relatedness, which of the following is the most accurate phylogenetic tree? d O C OB OA OD
