Related organisms descended from a common ancestor. For example, isolate M of HIV-1 (the human immunodeficiency virus) consists of at least ten clades. Imported from the Greek, klados, branch in 1911 in reference to the Tree of Life.

Also called a subtype. A clade is a group of related HIV viruses classified according to their degree of virus similarity. There are currently three groups of HIV-1 M, N, and O. Isolate M (major strai [..]

A phylogenetic grouping of organisms all of which appear to have descended from a single common ancestor and containing no organisms that are more closely related to any member of any other clade. An [..]

A clade is a group of related individuals.

A clade is a group of all the organisms that share a particular common ancestor (and therefore have similar features). The members of a clade are related to each other.

A set of species

A group of species or genes that includes all descendants of an ancestral species or gene. See

a group of evolutionarily related organisms (species, genera, or families) whose members share homologous features derived from a common ancestor. This means that a clade is monophyletic.

A set of species descended from a common ancestral species. Synonym of monophyletic group.

An ancestor (an organism, population, or species) and all of its descendants.

evolutionary branch of a cladogram that includes a single ancestor and all of its descendants living and extinct

(n) a group of biological taxa or species that share features inherited from a common ancestor

term coined by Julian Huxley, in terms of evolutionary branching and ancestry, to refer to the set of all organisms descended from a particular ancestor. In cladistics, a clade is a monophyletic group of organisms that includes all the descendants of a common ancestor as well as that ancestor itself. For example, birds, dinosaurs, pterosaurs (flyin [..]

see Monophyletic group.

A group composed of all the species descended from a single common ancestor; a monophyletic group.

    A monophyletic group (= a branch on a cladogram, diagnosed by at least one synapomorphy).

also called a subtype. A group of related HIV isolates classified according to their degree of genetic similarity (such as of their envelope proteins). There are currently two groups of HIV-1 isolates [..]

a subtype or strain of HIV. Different HIV clades exist in various regions of the world.

A group of organisms that includes all descendants of one common ancestor.

From Greek klados = branch. A branch of biological taxa or species that share features inherited from a common ancestor. A single phyletic group or line. Also cladus.

A clade is a branch in a cladogram, and also refers to a group of organisms which share a common ancestor and includes the ancestor and all the descendants of that ancestor.

The set of species descended from a particular ancestral species.

From the Greek word klados, meaning branch. A clade on the Y chromosome tree is also called a haplogroup.

(systematics) A group of animals or other organisms derived from a common ancestor species. * '''2001''', Ross H. Nehm, ''6: Linking Evolutionary Pattern and Development Process in Marginellid Gast [..]
