Abstract
URING a study of the B chromosomes of rye at pachytene D (LIMA-DE-FARIA, 1948) and a study of the A complement, also at pachytene (LIMA-DE-FARIA, unpublish'ed), the writer has been able to observe the existence of a definite structure in the centromere of these chromosomes.In my paper of 1948 I described the aentromere region of the standard fragment (a type of B chromosome) as ua very distinct gap without clear chromomeres )).This description of the centromere region was based on observations made in slides of average staining.Both the oentromere regions of the A and of the B chromosomes, in these slides, are apparently a structureless gap that is only faintly stained.As the observed intensity of stain in the centromere region was similar to that sometimes observed between the chromomleres (for instanoe, the parts on both sides of the knob of the standard fragment), I had already suspected a possible existence of chromomeres at the centromere, and for this reason I described the centromere region as cited above.

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.
