Which of the following statements about phylogenetic trees is not true.

. Sister taxa are always the result of the. The tree is polyphyletic. A cladogram does not represent the evolutionary time or the.

A monophyletic group consists of a common ancestor and some of its descendants. The statement B is one of As ancestors is false. Sister taxa always share a most recent common ancestor that is not shared with any other taxon on the phylogeny.

A paraphyletic group has not experienced lateral gene transfer. Descendants of organism d have legs. They are both descendants of one ancestor and can be termed as sister species Smith et al 2020.

I Descendant groups branches from the same node do not necessarily share any derived characters. A monophyletic group can be properly based on convergent features. Crocodile is related to a lizard but is not related to a bird E.

Which of the following statements isare true regarding a cladogram and a phylogenetic tree. Parsimony assumes that once a character changes it never reverses to the previous state. Which of the following statements regarding the construction of phylogenetic trees are true.

Asked Oct 7 2019 in Biology Microbiology by xoxoblair. Descendant groups branches from the same node do not necessarily share any derived characters. Crocodile is more closely related to a bird than to a lizard C.

Which of the following statements about phylogenetic trees is true. A cladogram and a phylogenetic tree both show possible relationships between organisms based from shared characteristics. Select all that apply.

The lizard is more closely related to the salamander than to the crocodile. False as reptiles are a paraphyletic group. This group does not include birds even though birds are thought to share a common ancestor with reptiles.

A tree shows the relative timing of divergences along a particular lineage. Based on the phylogenetic tree below which of the following statements is true. They can show which group of organisms diverged longest ago.

Crocodile is equally related to dinosaur and bird D. Biology questions and answers. Which of the following statements is always true about sister taxa on a phylogenetic tree.

II A monophyletic group can be properly based on convergent features. Sister taxa are always the result of speciation events that result in two new genera. They can show which groups of organisms are more advanced than other groups.

The phylogenetic tree shown here displays the major clades of chordates. The preferred phylogenetic tree under the parsimony method is the tree with the fewest branches. The ancestral group often has all the synapomorphies of the descendant species.

The traits being used must be homologous not analogous the tree should represent the least number of changes in characteristics monophyletic clades should be used the tree should be based on just on source of data. According to the phylogenetic tree B and A share a common ancestor. This group does not include birds even though birds are thought to share a common ancestor with reptiles.

It is only true to say that they are closely related since the ancestral lineages prior to them join into one lineage. The preferred phylogenetic tree under the parsimony method is the tree that requires the smallest number of evolutionary changes to explain the data. Which of the following statements is true about a phylogeny as represented by a phylogenetic tree.

Which statements about the phylogenetic tree are true. Imagine that a researcher has created two possible phylogenetic trees for a group of organismsone that hypothesizes that five character changes occurred in a given group and one that predicts only. Imagine that a researcher has created two possible phylogenetic trees for a group of organismsone that hypothesizes that five character changes occurred in a given group and one that predicts only.

Which of the following statements is true. Time is read from the terminals to the root of a tree. False as reptiles are a paraphyletic group.

A tree shows the relative timing of divergences in different lineages. The number of clades in a given tree is exponentially greater than the number of terminals. Which of the following statements is true about a phylogeny as represented by a phylogenetic tree.

Select all that apply. The number of clades in a given tree is twice the number of terminals C. They can show which groups of organisms are most closely related.

Crocodile is more closely related to a dinosaur than to a bird B. A paraphyletic group consists of a common ancestor and some of its descendants. Birds and ray-finned fishes have a notochord and.
