(biology) The state or act of dividing as a natural process of growth or a spontaneous action. (genetics) The act or process of duplicating or repeating a region in the genetic material or chromosome, as in gene duplication and chromosomal duplication. (pathology) A disorder in which a body part is duplicated, such as in diprosopus (a craniofacial duplication) and diphalia (a penile duplication).

Results from our forumGenome duplicationEvidence suggests that at some points in time most of species alive today undergone whole genome duplications. Presumably, these events occurred to prevent extinction of those species which threatened those species after diversification event(http://mbe.oxfordjournals.org/content/23/5/887.full.pdf+html). ...

Re: aneuploidy and polyploidy... plants suggests that this condition has not been able to adapt to higher life forms and so, isn't as complex or problematic. It only concerns the duplication of all chromosomes, not the absence or excessiveness of certain chromosomes. I really hope this helps and that the information isn't too ...

Evolution is not Darwinian... as we knew it but also another central tenet of the modern synthesis inherited from Darwin, namely gradualism. In a world dominated by HGT, gene duplication, gene loss and such momentous events as endosymbiosis, the idea of evolution being driven primarily by infinitesimal heritable changes in ...

Re: Evolution or De-evolution?... to autism, I think it’s time to rethink this conclusion. (http://www.ncbi.nlm.nih.gov/pubmed/16151044). My second problem is the idea of genome duplication. At first the genome duplication was said to be the driving force of evolution by providing the genetic material for mutations leading to ...
