How does a branching tree diagram divide organisms into groups?
A branching tree diagram, also known as a phylogenetic tree or cladogram, is a visual representation that groups organisms together based on their shared derived characteristics. This diagram illustrates the evolutionary relationships between different species or groups of organisms. The process of creating a branching tree diagram starts with identifying the shared derived characteristics among the organisms being studied. These characteristics are traits that are unique to a particular group of organisms and have been inherited from a common ancestor. Examples of derived characteristics could include the presence of feathers in birds or the possession of a backbone in vertebrates. Once the derived characteristics are identified, the diagram is constructed by placing the organisms into branches or clades based on their shared derived traits. The more closely related organisms will be grouped together on branches that are closer to each other, indicating a more recent common ancestor. Conversely, organisms that are less closely related will be placed on branches that are more distant from each other, showing a more distant common ancestry. The branching pattern of the tree diagram represents the evolutionary relationships between the organisms. The points at which branches meet, called nodes, represent common ancestors from which the different groups have diverged. The length of the branches can indicate the amount of evolutionary change or time that has passed since the divergence from a common ancestor. Branching tree diagrams are valuable tools in understanding the evolutionary history and relationships between organisms. They provide a visual representation of the shared derived characteristics that define different groups and allow scientists to study patterns of evolution and common ancestry. These diagrams are used in various fields such as biology, paleontology, and taxonomy to classify and identify the relationships between different organisms.
What do you call the type of diagram that assists you in predicting the traits of offspring?
Punnett Square
Why two or more taxa might have shared derived traits?
Because they share a common ancestor they split off from.
What is the main different between organisms that share many characteristics and organism that do not?
The more derived characteristics organisms share,the greater their degree a kinship. For instance,a derived characteristic in plants is the presence of the vascular tissue.Although all organisms share similar traits.
What are analogous characters derived from?
Analogous characters can be traced to a distant common ancestor. Although they may differ in appearance, and somewhat in function, the analogous characters (traits) developed from an earlier functional trait. (Example : fins in fish, hands and feet in humans)
Is a cladogram a branched diagram showing between groups based on ancestral and derived traits?
A cladogram is a branched diagram showing between groups based on ancestral and derived traits. A cladogram is a good way to show the relationship between a human hand, a bats wings, and a dolphins flipper.

What does a chladogram show about evolution?
By showing the evolutionary relationships and emergency of ancestral and derived traits in taxa of organisms. Nested hierarchies of relatedness in organisms.
What traits do drug molecules with chain branching have?
The potency of the drug decreases with branching. This is probably due to decreased pharmacokinetics and decreased pharmacodynamics.
Are shared derived traits found in members of the in group of a clade?
No, shared derived traits are not found in members of the in group of a clade.
What are the probable mode of inheritance from a pedigree diagram showing phenotypes?
The modes of inheritance are y-linked, x-linked, and mitochondrial. Inherited traits can then be recessive, dominant, or autosomal depending on how they are inherited.
What is the difference between derived trait and ancestral trait?
Derived traits are traits that appeared in the most recent common ancestor of the group and was passed on to it's decedents. Ancestral traits are inherited directly from the ancestor
Biologists use to create a cladogram?
derived traits
What is classical taxonomy?
hi my name is nbil einstein..based on what i have learn, classical taxonomy is use degree of morphological divergence to construct evolutionary diagram while cladistic taxonomy is only species sharing derived traits are group past a branch point for the last common ancestor and derived traits that evolve once,now shared only by the descendent of the ancestor of which it first evolve.
What traits do drug molecules with branching tend to have?
They are less lipophilic than their corresponding straight-chained molecule. This is show by how molecules with branching with lower Hansch hydrophobicity constant values than their straight-chained counterparts.
How do you know from a pedigree diagram if a trait is dominant or resessive?
The dominant traits in a genetic diagram are indicated by capital letters and the recessive traits are indicated by lower case letters.
Which traits was derived most recently on the evolutionary timeline?
Cladogram
