Association between the Tibetan Mastiff Monoamine Oxidase B Gene Single Nucleotide Polymorphism and Stranger-directed Aggressive Behaviour
Bibliographic record
Abstract
The aggressive behavior in Tibetan mastiffs and Labrador retrievers when approached directly by a stranger was tested by a behavioural test.The polymerase chain reaction-restriction fragment length polymorphism(PCR-RFLP)was adopted to detect monoamine oxidaes B(MAOB)gene exon 3 polymorphism,and their genotypes and allelic frequency were estimated among Tibetan mastiffs(aggression when a stranger approaches)and Labrador retrievers(non-aggression when a stranger approaches).These results indicated that genotypes and allelic frequency of the MAOB gene were not significantly different between the two breeds(P0.05).The result of χ2 showed that the Tibetan mastiff is biased significantly from Hardy-Weinberg equilibrium(P0.01),while the Labrador retriever fits the Hardy-Weinberg equilibrium(P0.05).Thus the behavioral differences seen in Tibetan mastiffs and Labrador retrievers when a stranger approaches may not relate directly to the MAOB gene T199C polymorphism.

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.
