What do the horizontal lines on the phylogenetic tree represent?
60) The following question refers to this phylogenetic tree, depicting the origins of life and the three domains. Horizontal lines indicate instances of gene or genome transfer.
How was This phylogenetic tree constructed by comparing sequences?
This phylogenetic tree was constructed by comparing sequences for a homologous gene involved in development. Select the correct statement. A. A frog is the ancestor of both a mouse and a chicken.
Which statement best describes Linnaeus’s view of species classification?
Linnaeus was a "fixist" who believed that species remained fixed in the form in which they had been created. Linnaeus would have been uncomfortable with A) classifying organisms using the morphospecies concept.
What is a monophyletic taxon?
The term "monophyletic" refers to a taxon that includes an ancestral species and all of its descendants. C. The term "monophyletic" refers to a taxon that includes an ancestral species and all of its descendants.
Is the nucleotide sequence of this gene in a mouse more similar to the sequence in a
The nucleotide sequence of this gene in a mouse is more similar to the sequence in a chicken, and both are less similar to the nucleotide sequence of this gene in a frog. This figure shows a phylogenetic tree of birds and their close relatives. Identify the monophyletic taxon.
