Comparative transcriptome profiles of four sexually size dimorphic fish
Bibliographic record
Abstract
Sexual size dimorphism is widespread in fish species. Although sex growth differences in multiple species have been studied successively, the commonalities of regulatory mechanisms across sexually dimorphic species are unknown. In this study, we performed RNA-seq analysis of four representative fish (loach, half-smooth tongue sole, yellow catfish, and Nile tilapia) with significant growth differences between females and males. Clean reads were identified from four fish species, ranging from 45,718,052 to 57,733,120. Following comparison transcriptome analysis, there were 1,132 and 1,108, 1,290 and 1,102, 4,732 and 4,266, 748 and 192 differentially expressed genes (DEGs) in the brain and muscle of loach, half-smooth tongue sole, yellow catfish, and Nile tilapia, respectively. Furthermore, the expression levels were validated by quantitative real-time PCR (qRT-PCR). Comparative transcriptome profiles of four fish described here will provide fundamental information for further studies on the commonalities of sexually size dimorphic fish in regulating growth differences between females and males.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
