Abstract
Using four repetitive sequences, we compared DNAs isolated from Mus caroli, M. cookii, M. hortulanus, M. musculus, M. pahari, M. saxicola, and M. spretus. Except for B1, these probes showed species-specific hybridization patterns. Mouse interspersed fragment (MIF) sequences were present in all species examined, but those defined by the 1.3-kb EcoR1 band were fewer in M. pahari and M. saxicola than in the other species. The Y-chromosomal probe showed male-specific accumulation only in M. hortulanus, M. musculus, and M. spretus, which are known to be closely related. The genetic difference between M. spretus and the other two species (M. hortulanus and M. musculus) was clearly demonstrated by a M. musuclus centromeric sequence that hybridized strongly to M. hortulanus and M. musculus DNA but was underrepresented in the genome of M. spretus. These results may suggest the usefulness of these repetitive sequences in the classification of Mus species that display only subtle morphological differences.

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 it
