This is a monophyletic group.
A group of replicators consisting of (1) their most recent common ancestor (the founder) and (2) all offspring of members of the group (that is, all descendants of the founder). A monophyletic group. A descent group of chain letters.
A group of monophyletic organisms or DNA sequences that include all of those in the analysis that are descended from a particular common ancestor.
A lineage of organisms or alleles that comprises an ancestor and all its descendants.
(1) According to the rigorous definition, a taxon consisting of a single species and all its descendants representing a monophyletic branch on an evolutionary tree. (2) In looser usage, as above, except that some descendants are not represented. (3) In reference to extant organisms, a subgroup of organisms from among a larger group under consideration sharing a common ancestor not shared by the other organisms in the group.
any distinct branch or grouping of branches in a phylogenetic tree
A clade (or subtype) is a group of related HIV isolates, classified according to their degree of genetic similarity (such as the percentage of identity within their envelope genes). There are currently three groups of HIV-1 isolates: Group M (major strains) consists of at least ten clades, A through J, with clade B the most common form in the West; Group O (outer strains) may consist of a similar number of clades; Group N is a new HIV-1 isolate that cannot be categorised in either group M or O.
An ancestor (an organism, population, or species) and all of its descendants.
Also called a subtype. A clade is a group of related HIV isolates (see Isolate) classified according to their degree of genetic similarity (such as the percentage of identity within their envelope genes). There are currently three groups of HIV-1 isolates: M, N, and O. Isolate M (major strains) consists of at least ten clades, A through J. Group O (outer strains) may consist of a similar number of clades. French researchers reported the discovery of a new HIV-1 isolate that cannot be categorized in either group M or O. The new isolate was found in a Cameroonian woman with AIDS. They suggested that this new isolate be classified as group N (for new or for "non-M-non-O").
Group of organisms defined on the basis of common ancestry as indicated by shared, derived characters (synapomorphies).
a group of organisms consisting of an organism and all of its descendants.
For an unrooted tree, a clade is a group of taxa that may be separated from the rest of the tree by breaking a single branch. For a rooted tree, a clade is all taxa in a subtree of the tree.
Group of organisms all descended from a single common ancestor.
(Also called sub-type) A group of related HIV isolates classified by their degree of genetic similarity. There are two major groups of HIV-1 isolates, called M and O. Group M consists of at least eight clades, A through H. (See isolate.)
Show clades: A group that is defined by features exclusive to all its members, and that distinguish the group from all others. In evolutionary terms, a clade is a monophyletic group.
From the Greek word klados, meaning branch. A clade on the Y chromosome tree is also called a haplogroup.
a group of biological taxa or species that share features inherited from a common ancestor
a biological group of species with a common evolutionary ancestor
a cluster of taxa derived from a single common ancestor
a daughter species, a related descendant
a grouping of organisms that includes an ancestor and all of its descendents
a grouping that includes a common ancestor and all the descendents (living and extinct) of that ancestor
a group of organisms which share a common ancestor and which includes all descendants of that ancestor
a monphyletic group
a natural taxon of organisms bound in space and time a
an evolutionary branch that includes a common ancestor and all its descendent species
a purported monophyletic group in which all members share a single common ancestor at some unidentified point in the past
a "natural group" or phylogenetically defined group of organisms. A clade is usually defined as a particular organism "and all of its descendants." This apparantly innocuous concept, introduced to systematics by Willi Hennig, has completely changed the way systematics is done and has fundamentally altered the way we view evolutionary change. To understand why, see Cladograms.
Group of organisms which share a common ancestor and form a phylogenetic lineage. In terms of HIV, the term "clade" is often used to refer to a sub-type.
A group comprising all the evolutionary descendants of a common ancestor. Also called "clan" or haplogroup.
(from Greek klados "branch"): a group of biological taxa, such as a species, that are considered to share a common ancestor
A group comprising all the evolutionary descendants of a common ancestor. In the scientific literature, clades are given letter and number designations, like H, U4 and L3a1. Professor Sykes introduced the concept of giving names to the originators of the clades, like Helena, Ulrike and Lamia, and using the term "clan" instead of clade to describe the group. Oxford Ancestors continues the use of this convention in both its maternal and paternal ancestry services.
a group of organisms that share a common ancestor; lineage; a monophyletic group
Groups with common ancestry - taxon A and taxon B have common ancestor. cladistics works on min of 3 taxa - question is how recent. Clade is always monophyletic
A set of species descended from a common ancestral species. A clade is also a synonym for a monophyletic group.
A group of organisms, such as a species, whose members share homologous features derived from a common ancestor. The avian virus H5N1 clade 1 includes human and bird isolates from Vietnam, Thailand, Cambodia, Laos, and Malaysia. Clade 2 viruses have been identified in bird isolates from China, Indonesia, Japan, and South Korea.
a subtype or strain of HIV. Different HIV clades exist in various regions of the world.
A subtype of HIV made up of a group of related HIV isolates classified according to their degree of genetic similarity (such as the percentage of identity within their envelope genes). There are currently 3 groups of HIV-1 isolates M, N, and O. Isolate M (major strains) consists of at least 10 clades, A through J. Group O (outer strains) may consist of a similar number of clades.
A monophyletic group (= a branch on a cladogram, diagnosed by at least one synapomorphy).
A group of organisms which includes the most recent common ancestor of all of its members and all of the descendants of that most recent common ancestor.
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, M and O. M consists of at least nine clades, A through I. Group O may consist of a similar number of clades. (See also isolate.)
monophyletic group containing an ancestral taxon and all of its descendants.
group with a common ancestor, i.e., a single evolutionary branch
see Monophyletic group.
A related group of animals with a common ancestor, e.g. the dinosaurs all evolved from a single common ancestor, and are a 'clade'.
A set of species descended from a common ancestor.
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
In cladistics, a clade is a group of organisms consisting of a single common ancestor and all the descendants of that ancestor. Any such group is also considered a monophyletic group of organisms, and can be modelled by a cladogram, a diagram of the organisms in the form of a tree.
Clade is a science fiction novel written by Mark Budz, published in 2003. In Clade, an environmental disaster called the Ecocaust has caused sea levels to rise and causing additional strains on human resources. The government, in response, becomes more restrictive on human freedoms, and this novel explores what happens after the Ecocaust.
