Abstract
ABSTRACT The expression of unique isoform of pituitary transcription factor (Pit‐1) is reported in the chicken and turkey. However, it is not well known whether this isoform is expressed in the other avian species. In the present study, complementary DNA (cDNA) and genomic DNA, of Pit‐1 of domesticated duck, were cloned and sequenced. Duck Pit‐1α was found to have 93.3, and 92.4% sequence identity at the cDNA level to Pit‐1α of chicken and turkey, respectively. The predicted amino acid sequence had 96.7% similarity with a comparable region of Pit‐1α of both chicken and turkey. Based on the cDNA sequence, the genomic structure of the gene was characterized. The duck Pit‐1 gene consisted of seven exons and six introns. Sequence analysis of the duck Pit‐1 gene allowed for the design of a forward primer for amplification of Pit‐1γ, which is synthesized from an alternative transcription initiation site in galliforms. Reverse transcription of total RNA followed by polymerase chain reaction successively amplified a 984 bp product of Pit‐1γ cDNA, which encoded a peptide of 326 amino acids. These results suggest that the expression of Pit‐1 isoform originates from a different site of transcription initiation, which is not unique to galliforms but is observed in other avian species including anseriforms.

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 it
