When descendants from the LCA share mutated homologs of the original duplicated genes then those genes are considered paralogs. Definition. 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. After duplication, the paralogous genes can keep the same function (for example, the multiple copies of ribosomal RNA genes found in paralogous genes.
2019-12-25 · Paralogous genes are homologous genes diverged within a single species. They have evolved due to a mutation that occurred in the genetic duplication process. 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.

A particular paralog in one organism can be orthologous to a gene in another organism, or it could have arisen independently in an ancestor, through a gene duplication event. AKA: paralogous locus Two genes or clusters of genes at different chromosomal locations in the same organism that have structural similarities indicating that they derived from a common ancestral gene and have since diverged from the parent copy by mutation and selection or drift.

Unlike orthologous genes, a paralogous gene is a new gene that holds a new function.

Molecular characterization of the four clusters has shown that they are evolutionarily related with respect to sequence, organization, and expression, suggesting they arose by duplication and divergence.

Unlike orthologous genes, a paralogous gene is a new gene that holds a new function. 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.
