The two genes that exist after a gene duplication event are called paralogs and usually code for proteins with a similar function and/or structure. By contrast, orthologous genes present in different species which are each originally derived from the same ancestral sequence. (See Homology of sequences in genetics). It is important (but often difficult) to differentiate between paralogs and orthologs in biological re… WebChromosomal ( whole-genome) duplication is thought to arise by the breakdown of the normal mitotic or meiotic process.
