Homeologous is a term used to describe sequences or genes that share similar features due to being derived from the same ancestor, but are not identical. Some synonyms for homeologous include paralogous, orthologous, and homologous. Paralogous refers to genes that have duplicated within a single genome, while orthologous genes are found in different species, but perform similar functions. Homologous refers to genes that share a common ancestry and are related through descent. These terms are commonly used in genetics and evolutionary biology to describe relationships between genes and genetic sequences. Homeologous genes can play an important role in the evolution of new traits and species.
