| Abstract |
Gene duplication generates new genetic material which, if retained after duplication, may contribute to organismal evolution. A whole-genome duplication occurred in the ancestry of teleost fish and consequently there are many duplicated genes in teleost genomes. Indeed, it has been proposed that the evolutionary diversification of teleost fish may have been stimulated by the fish-specific genome duplication (FSGD). However, it is not clear which factors determine which genes are retained as duplicate copies and which return to a singleton state after duplication. In the present study, gene complexity, in terms of encoded protein length and functional domain number, is compared between duplicate and singleton genes for nine well-annotated teleost genomes. A total of 933 gene families with retained duplicates and 4590 singleton gene families are analysed. Genes with retained duplicates are found to be significantly longer (27.9-38.2%) and to have more functional domains (20.5-26.5%) than singleton genes in all the nine teleost genomes, suggesting that genes encoded longer proteins with and more functional domains were preferentially retained after whole-genome duplication in teleosts. This differential retention of duplicated genes will have increased the genomic complexity of teleost fish after FSGD which, together with differential duplicated gene retention as a lineage-splitting force, may have greatly contributed to the successful diversification of teleost fish. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 12 May 2017.
All research outputs
#7,527,793
of 22,971,207 outputs
Outputs from Journal of Molecular Evolution
#454
of 1,447 outputs
Outputs of similar age
#119,407
of 310,791 outputs
Outputs of similar age from Journal of Molecular Evolution
#3
of 9 outputs
Altmetric has tracked 22,971,207 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,447 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.2. This one is in the 29th percentile – i.e., 29% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 310,791 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 53% of its contemporaries.
We're also able to compare this research output to 9 others from the same source and published within six weeks on either side of this one. This one has scored higher than 6 of them.
