The 5S rDNA high dynamism in Diplodus sargus is a transposon-mediated mechanism. Comparison with other multigene families and Sparidae species.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
There has been considerable discussion in recent years on the evolution of the tandemly repeated multigene families, since some organisms show a concerted model whereas others show a birth-and-death model. This controversial subject extends to several species of fish. In this study, three species of the Sparidae family (Pagrus pagrus, P. auriga and Diplodus sargus) and an interspecific hybrid (P. pagrus (♀) × P. auriga (♂)) have been studied at both molecular and cytogenetic level, taking three different multigene families (5S rDNA, 45S rDNA and U2 snDNA). Results obtained with the 5S rDNA in P. pagrus and P. auriga are characterized by a considerable degree of conservation at the two levels; however, an extraordinary variation was observed in D. sargus at the two levels, which has never been found in other fishes studied to date. As a consequence of this, the evolutionary model of the multigene families is discussed considering the results obtained and others from the bibliography. The result obtained in the hybrid allowed the recombination frequency in each multigene family to be estimated.
