Ohno's original model [ 25] intuitively suggested that duplication facilitated novel functions (neofunctionalisation) through the relaxation of purifying selection due to redundancy after duplication.
The increase of plant complexity with duplication events (Freeling et al. 2006) may partly be the result of duplication facilitating increasingly complex regulatory networks (Veron et al. 2007).
Moreover, they should systematically collect information on the activities of other funders to avoid duplication, facilitate collaboration and allow evaluation of interventions across funding institutions.
The relatively small genome size of sorghum (736 Mb, about twice that of rice), high genetic diversity, diploidy, minimal level of gene duplication facilitating functional assignment, and ability to serve as a model for crops with the C4 carbon-fixing metabolism such as maize, pearl millet, and sugar cane, justified its choice as the third plant species to have its genome sequenced.
Regardless of the controversy regarding the nature of primordial cell-cycle regulators, the results presented here suggest that control over cell cycles became more important in large and long-lived animals and that expansion of the cyclin/CDK network, which occurred through genome duplication, facilitated fine-tuning of that control.
In vertebrates, gene duplications facilitated sub-functionalization compared to the ancestral invertebrate actinin, as well as neo-functionalization.
The human hsp70-gene family is in the main the result of multiple duplications facilitated by frequent retrotransposition events of a single highly expressed gene, HSPA8.
It has been suggested that segmental duplications facilitate chromosome rearrangements and correlate with CNVs; therefore the lack of segmental duplications in the avian genome[ 1] might explain the low number of chromosomal rearrangements in Galliformes in particular and birds in general.
Its mechanisms are also worthy of duplication: PharMosaic facilitates relationships among pharmaceutical companies, schools of pharmacy, business schools, high schools, colleges, and universities to further its goals.
