- adj. Corresponding or similar in position, value, structure, or function.
- adj. Biology Similar in structure and evolutionary origin, though not necessarily in function, as the flippers of a seal and the hands of a human.
- adj. Immunology Relating to the correspondence between an antigen and the antibody produced in response to it.
- adj. Genetics Having the same morphology and linear sequence of gene loci as another chromosome.
- adj. 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.

- adj. Being of the same typical structure; having like relations to a fundamental type to structure; as, those bones in the hand of man and the fore foot of a horse are homologous that correspond in their structural relations, that is, in their relations to the type structure of the fore limb in vertebrates.

- In pathology, noting a neoplasm composed of tissues of the same type as those of the part from which it springs: distinguished from heterologous.

Professor Heer has not ventured to identify any of this vast assemblage of Miocene plants and insects with living species, so far at least as to assign to them the same specific names, but he presents us with a list of what he terms homologous forms, which are so like the living ones that he supposes the one to have been derived genealogically from the others.
Comparing aligned positions in homologous protein sequences two different behaviors are found:
With the help of Evans, they both set up ES cell culture for use in homologous recombination experiments.
We knew there's a mechanism called homologous recombination, that biology uses to repair DNA, that can put pieces together.
They are called homologous because they have similar parts in similar relations.
Mr. Lankester also adduces the close resemblance of the parts on the right and left sides of the body, and in the successive segments of the same individual animal; and here we have parts commonly called homologous, which bear no relation to the descent of distinct species from a common progenitor.
All new formations built of cells which continue true to the parent type we may call homologous new formations; while those which depart from the parent type or undergo degenerative changes we may designate heterologous.
Scientists have developed a successful test for another type of manipulation called homologous blood doping.
The protein produced by the Brca1 gene participates in an important DNA repair pathway called homologous recombination (HR).
The gene content and gene order of LyxyMNPV were similar to those of LdMNPV, with 151 ORFs identified as homologous to those reported in the LdMNPV genome.
