We observed three distinct patterns of duplication events for B3 genes according to their duplication origin: genes that were duplicated and inserted in different chromosomes, genes that were duplicated and inserted in the same chromosome and genes that were duplicated in tandem.
To examine sequence changes that cause subcellular relocalization, and characterize expression and sequence evolution in another gene whose product has been relocalized, we studied a pair of calcium-dependent protein kinase genes, CPK2 (andg10660) and CPK1 (Athat4870) that were duplicated by the α-WG duplication.
These copies can be considered as "ohnologs" since they are derived from ancestral kit and kitl genes that were duplicated during the teleost-specific whole-genome duplication event (Mellgren and Johnson 2005; Braasch et al. 2006; Hultman et al. 2007).
If the multiple vertebrate paralogues of the components of the signaling system arose by genome duplication events what was the evolutionary origin of the genes that were duplicated by those events?
The analysis of the duplicated Hox genes in the paddlefish provides a remarkable opportunity to investigate the proximate changes in molecular evolution that occur relatively shortly after a duplication event and to compare those processes with the same genes that were duplicated independently before the origin of teleosts approximately 250 Myr earlier.
CNET said it would eliminate certain businesses that were duplicated when it acquired ZDNet last fall, as well as support staff in departments like financial services and human resources.
Kathy Willis, director of science at Kew, said many of the job losses involved positions that were duplicated at different sites, a legacy of staff being transferred from temporary to permanent contracts over the past 10 years.
Hipsters in the communist days wore jeans and branded sneakers, like Nikes and Pumas, which sailors brought back from the West, along with vinyl records that were duplicated on to tape at an amazing speed.

Several "brainy" genes that were duplicated in a tiny sea creature nearly 550 million years ago may have led to the massive expansion in intelligence in vertebrate species, two new studies have found.
While longer reads reduce this problem to some extent, for genes that were duplicated very recently even reads longer than 100 bp will not improve the situation.
