Abstract
A common cytogenetic finding in both Q-banded and solid Giemsa-stained preparations of pronuclear chromosomes obtained from cross-species fertilization of hamster oocytes by human sperm is the presence of a variable-length "gap" in the centromeric region. Scanning electron microscopy was used to investigate these altered chromosomal regions. The centromere in most eukaryotic organisms appears as a constricted region approximately 200-300 nm in diameter. In contrast, the gap portion of the centromeric region of pronuclear chromosomes was found to contain a chromatin fiber with a diameter of 80-150 nm. The detection of this fiber confirms that the chromosome arms are continuous, and the size of the fiber explains the gap appearance in the light photomicrographs. The morphology of the fiber is consistent with the concept that the normal chromatin packaging has been altered in varied regions within the centromere of these chromosomes.

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
