homologous
ho·mol·o·gous H0257800 (hə-mŏl′ə-gəs, hō-)adj.1. Corresponding or similar in position, value, structure, or function.2. Derived from the same species: a homologous graft.3. Biology Similar in structure and evolutionary origin, though not necessarily in function, as the flippers of a seal and the hands of a human.4. Immunology Relating to the correspondence between an antigen and the antibody produced in response to it.5. Genetics a. Relating to chromosomes that have the same morphology and linear sequence of gene loci.b. Relating to genes that are derived from a common ancestor.6. Chemistry Belonging to or being a series of organic compounds, each successive member of which differs from the preceding member by a constant increment, especially by an added CH2 group.
[From Greek homologos, agreeing : homo-, homo- + logos, word, proportion; see leg- in Indo-European roots.]homologous (həʊˈmɒləɡəs; hɒ-) , homological or homologicadj1. having a related or similar position, structure, etc2. (Chemistry) chem (of a series of organic compounds) having similar characteristics and structure but differing by a number of CH2 groups3. (Medicine) med a. (of two or more tissues) identical in structureb. (of a vaccine) prepared from the infecting microorganism4. (Biology) biology (of organs and parts) having the same evolutionary origin but different functions: the wing of a bat and the paddle of a whale are homologous. Compare analogous25. (Mathematics) maths (of elements) playing a similar role in distinct figures or functions ˌhomoˈlogically advho•mol•o•gous (həˈmɒl ə gəs, hoʊ-)
adj. 1. having the same or a similar relation; corresponding, as in relative position or structure. 2. Biol. corresponding in structure and in evolutionary origin but not necessarily in function, as the wing of a bird and the foreleg of a horse (opposed to analogous). 3. having the same alleles or genes in the same order of arrangement. 4. of the same chemical type, but differing by a fixed increment of an atom or a constant group of atoms. 5. pertaining to an antigen and its specific antibody. [1650–60; < Medieval Latin homologus < Greek homólogos agreeing; see homo-, -logous] ho·mol·o·gous (hə-mŏl′ə-gəs)1. Similar in structure and evolutionary origin but having different functions, as a human's arm and a seal's flipper. Compare analogous.2. Being a set of two pairs of chromosomes, one pair from the female parent and one from the male parent, having genes for the same trait in the same positions. Genes on homologous chromosomes may not have the same form, however. For example, one set of homologous chromosomes may contain a gene for brown eyes and the other for blue eyes.Thesaurus| Adj. | 1. | homologous - having the same evolutionary origin but not necessarily the same function; "the wing of a bat and the arm of a man are homologous"biological science, biology - the science that studies living organismsanalogous - corresponding in function but not in evolutionary origin; "the wings of a bee and those of a hummingbird are analogous"heterologic, heterological, heterologous - not corresponding in structure or evolutionary origin | | 2. | homologous - corresponding or similar in position or structure or function or characteristics; especially derived from an organism of the same species; "a homologous tissue graft"autologous - derived from organisms of the selfsame individual; "autologous blood donation"heterologous - derived from organisms of a different but related species; "a heterologous graft" |

In chemistry, denoting a single chemical series, differing by fixed increments. 3. In genetics, denoting chromosomes or chromosome parts identical with respect to their construction and genetic content. 4. In immunology, denoting serum or tissue derived from members of a single species, or an antibody with respect to the antigen that produced it. 5.

Of transplantation in which the donor and recipients are of the same species. homologous (of organs, or structures) deriving from the same evolutionary origins. For example, the forelimb of a quadruped, the human arm, the wing of a bird, are said to be homologous (see PENTADACTYL LIMB). Usually similarities are seen best in embryonic development, and are regarded by taxonomists as indications of relationships between present-day organisms.homologous
