Genetic Variations in the Bovine Fatty Acid Desaturase 6 (FADS6) Are Associated with Fatty Acid Composition in Hanwoo Cattle
Bibliographic record
Abstract
The purpose of this study was to discover genetic variants in the bovine fatty acid desaturase domain family member 6 (FADS6) gene and to test for associations with fatty acid composition (FAC) as well as carcass traits such as backfat thickness (BFT) and marbling scores (MAR). 90 Hanwoo steers were used in the study, and sequence analyses detected 4 genetic variants in intron 2 (approximately 10,890 bp) of FADS6. The FADS6 SNPs showed no significant departures from HWE (Hardy-Weinberg Equilibrium) except g.57772511C > T that did not have heterozygous genotypes. Genotypes of g.57770744A > G and g.57772511C > T were significantly associated with Vaccenic (C18:ln7), Palmitoleic (C16:ln7), and Stearic (C18:0) acids. The analysis confirmed dominance and additive effects for the g.57770744A > G and g.57772511C > T segments, respectively. A positive correlation (31.1%, P = 0.003) between BFT and Linolenic acid (C18:3n3) and a negative (-36.5%, P < 0.001) correlation between MAR and Eicosenoic acids (C20:1n9) were observed.

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.
