Phylogeny; a derived trait that is unique to one taxon or lineage is called an autapomorphy. Homoplasy, synapomorphy, and plesiomorphy are other terms used in phylogenetics. A monophyletic group refers to a group of organisms that includes a common ancestor and all of its descendants.
Sri K.
A synapomorphy is a: a. Primitive trait that is shared between taxa (i.e., taxa are similar with respect to the trait) because it has been inherited from a distant common ancestor of those - often called a shared, primitive character. b. Derived or novel trait that is shared between taxa (i.e., taxa are similar with respect to the trait) because it has been inherited from the last common ancestor of those taxa - often called a shared, derived character. c. Trait that is shared between taxa (i.e., taxa are similar with respect to the trait) but has not been inherited from a common ancestor - often called a parallelism or a convergence. d. A trait that provides no information about phylogeny. e. A trait that provides misleading information about phylogeny.
Adi S.
Synapomorphy is characteristically present in that shared by its immediate counterparts. Homology is a trait that is among species due to common ancestry.
