Genetic Variation in the Growth Hormone Promoter Region of <i>Anas platyrhynchos</i>, a Duck Native to Myanmar
Bibliographic record
Abstract
Genetic variations were detected in duck growth hormone (GH) gene promoters at 8 positions in the genome of ducks from 3 regions (Mandalay, Khayan, and Sittwe) in Myanmar. Different frequencies were detected in the 3 regions. Higher frequencies were detected at positions, 244, 294, 586, and 665 of the GH promoter from both Mandalay and Khayan than in the ducks from Sittwe. The duck populations of Mandalay and Khayan have been partially selected for egg production by introducing a layer strain of Thailand native ducks, whereas that of Sittwe has been maintained without introduction of any other strain. The differences in the frequency of variations reflect that the breeding method in each region is unique. Since most of the variations were located in sequences similar to the promoters found in chickens and turkeys, variations in the promoter may affect laying performance by changing the expression of GH mRNA levels in the anterior pituitary gland.

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.
