Centromeric Satellite DNA in Flatfish (Order Pleuronectiformes) and Its Relation to Speciation Processes
Bibliographic record
Abstract
Two new centromeric satellite DNAs in flatfish (Order Pleuronectiformes) have been characterized. The SacI-family from Hippoglossus hippoglossus, restricted to this species, had a monomeric size of 334 base pair (bp) and was located in most of the centromeres of its karyotype. The PvuII-family, with a monomeric size of 177 bp, was initially isolated from the genome of Solea senegalensis, and fluorescent in situ hybridization (FISH) localized the repeat to centromeres of most of the chromosomes. This family could only be amplified in 2 other species of the genus Solea (Solea solea and Solea lascaris). Molecular features and chromosomal location indicated a possible structural and/or functional role of these sequence repeats. The presence of species-specific satellite-DNA families in the centromeres and their possible role in the speciation processes in this group of fishes is discussed.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
