(for example, A1 and B2), rather than orthologs (for example, A1 and A2). This would seem ill advised because we are dealing with a particular relationship between paralogs, yet the term … WebFeb 19, 2002 · Briefly, orthologs are genes in different organisms which are direct evolutionary counterparts of each other. Orthologs were inherited through speciation, as opposed to paralogs which are genes in the same organism which evolved by gene duplication [6, 3, 2]. After duplication, paralogous proteins experience weaker …
