| homology |
Clad. Any characteristic shared between two that whose similarity is due to common descent. Opposed to homoplasy. In cladistics, both homology and homoplasy are determined a posteriori with reference to a particular phylogeny that maximizes homology and minimizes homoplasy.

| homology r.’s |
regions of immunoglobulin heavy and light chains containing about 110 amino acid residues and forming compact globular domains stabilized by one intrachain disulfide bond; they have a high degree of sequence homology and similar three-dimensional structure. Each variable region (VH and VL) of heavy and light chains and the light chain constant region (CL) are coextensive with a single homology region. Heavy chain constant regions are composed of three (in γ, δ, and α chains) or four (in μ and ε chains) homology regions, CH1, CH2, CH3, and CH4, and a hinge region separating CH1 and CH2.

| homology |
Homologs have common origins but may or may not have common activity. Genes that share an arbitrary threshold level of similarity determined by alignment of matching bases are termed homologous. They are inherited from a common ancestor which possessed the structure. This may be difficult to determine when the structure has been modified through descent. Note: homology is a qualitative term (something is either homologous or not), while similarity is the corresponding quantitative term. ...
