3. pertaining to an antibody and the antigen that elicited its production.

ho·mol·o·gous

(hō-mol'ō-gŭs), Corresponding or alike in certain critical attributes.
1. In biology or zoology, denoting organs or parts corresponding in evolutionary origin and similar to some extent in structure, but not necessarily similar in function.
2. 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. Proteins having identical or similar functions (particularly with respect to proteins from different species).

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.

homologous

homologous

1. Of corresponding structure, position, function or value.
2. Having the same consecutive sequence of genes as another chromosome.
3. Belonging to a series of organic compounds of which the successive members differ by constant chemical increments.
4. 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

1. corresponding in structure, position, origin, etc.
2. derived from an animal of the same species but of different genotype; allogeneic.

Consider the obstacles involved: The genes that initiate wing formation in a bird or insect may do nothing in a human (or may activate homologous organs, such as arms); these genes would have to be altered to allow a wingspan of some 20 feet; and the human's entire genome would have to be transformed to create the lighter bones and stronger muscles required for flight.
