Paralogous genes (or paralogs) are a particular class of homologous genes. They are the result of gene duplication and the gene copies resulting from the duplication are called paralogous of each other. Paralogous genes are genes that are related via duplication events in the last common ancestor (LCA) of the species being compared. They result from the mutation of duplicated genes during separate speciation events. When descendants from the LCA share mutated homologs of the original duplicated genes then those genes are considered paralogs. Paralogous genes often belong to the same species, but this is not necessary. For example, the hemoglobin gene of humans and the myoglobin gene of chimpanzees are paralogs.

Paralogous genes

Therefore, they are present within the same genome. Paralogous genes may carry out different functions. Two genes are to be paralogous if they diverged after a duplication event. The original quotation is by Walter Fitch (1970, Systematic Zoology 19:99-113): "Where the homology is the result of gene duplication so that both copies have descended side by side during the history of an organism, (for example, alpha and beta hemoglobin) the genes should be called paralogous (para = in parallel). An example of how paralogous genes can confound species tree. We start with a single (purple) gene: at a particular point in time, this gene duplicates into a red and a blue form. Each of these genes then evolve and spread into four separate descendent species (A, B, C and D) but not in entirely the same way.

Paralogous genes often belong to the same species, but this is not necessary. For example, the hemoglobin gene of humans and the myoglobin gene of chimpanzees are paralogs. Paralogs can be split into in-paralogs (paralogous pairs that arose after a speciation event) and out-paralogs (paralogous pairs that arose before a speciation event).

Alternatively, strong purifying selection against mutations that modify gene function can also prevent duplicated genes from diverging. For example, based on observations from the genomic databases for several eukaryotic species, Lynch and Conery estimated that in eukaryotes the average rate of gene duplication is approximately 0.01 per gene per million years (i.e.
