Evolution by gene and genome duplication

WebNov 10, 2000 · Abstract. Gene duplication has generally been viewed as a necessary source of material for the origin of evolutionary novelties, but it is unclear how often gene duplicates arise and how frequently they evolve new functions. Observations from the genomic databases for several eukaryotic species suggest that duplicate genes arise at … Websignificance of gene and genome duplications and the contribution of these mechanisms to the advances in genomic and organismal evolution. The year 2000 marked the 30th anniversary of the publication of Susumu Ohno’s seminal book Evolu-tion by gene duplication (Ohno, 1970). Sadly, that year was also the year in which Ohno passed away.
