a character which is shared by all basal members of a clade and is derived from their common ancestor. A synapomorphy may be secondarily lost in later descendants. Only a synapomorphy may be used to infer phylogeny
unique derived character.--------------------Y-Z
These are characters that are shared by a group of sequences due to recentness of common ancestry.
A shared derived character state that is indicative of a phylogenetic relationship among two or more OUT's.
A shared, derived character state. In this code, a synapomorphy is a shared, derived character state inherited from a common ancestor that possessed that state; a shared, independently derived character state is not considered to be a synapomorphy in the sense the term is used in this code.
Character, shared between two or more groups of organisms, that was derived from earlier characters. Evolutionarily derived (“new†or “novelâ€) anatomical trait. Used in cladistic (phylogenetic) classification system.
A homologous derived character shared by two or more, but not all, taxa in the ingroup.
In cladistics a derived or specialized character ( apomorphy) shared by two or more groups which originated in their last common ancestor. Compare to autapomorphy more "
shared derived trait ( apomorphy); a derived character that is shared between organisms; compare to autapormorphy
A shared derived character; a character that is shared by two or more taxa (e.g. species) and evolved in their common ancestor, thus indicating their common evolutionary descent (and distinguishing them from other taxa that do not have this character state). return to the top of the page
An apomorphy shared by two or more terminal taxa; thus diagnoses a clade or monophyletic group (see also homology).
Shared derived characters that are regarded as homologous are called synapomorphies, e.g. the presence of mammary glands in all three lineages of mammals (monotremes, marsupials and placentals). These sorts of characters suggest a close relationship of the organisms that share them.
an apomorphy shared by two or more species or clades.
A character which is derived, and because it is shared by the taxa under consideration, is used to infer common ancestry.
Synapomorphy ( meaning "shared form") is a derived (new) character shared by groups. A synapomorphy can be used to infer common ancestry.
In evolutionary biology, a synapomorphy is a derived character state shared by two or more terminal groups (taxa included in a cladistic analysis as further indivisible units) and inherited from their most recent common ancestor.
