- (chemistry) Belonging to a series of aliphatic organic compounds that differ only by the addition of a CH2 group.
- (genetics) Having the same morphology as another chromosome; relating to a homologue.
- (biology) For a discussion of the use of the term "homology" (and by association "homologous") in biology, see: Patterson, Colin. "Homology in Classical and Molecular Biology."
