Abstract
The mouse Y chromosome is rich in repetitive sequences. We describe a new highly male-specific BALB/c mouse sequence named 142-5. The distribution of 142-5 related sequences, which appeared to be repeated at least 100 times in the male genome of Mus musculus, was visualized on the Y chromosome by in situ hybridization. Their accumulation patterns in the genus Mus showed that the sequences evolved quickly and suggested that they might prove useful for detecting genetic differences between closely related species. To test this hypothesis, we isolated 20 additional sequences from three mouse species (M. musculus, M. spicilegus, and M. spretus) and compared their nucleotide sequences using three different computer programs. It was found that the sequences were remarkably similar but could be divided into four subgroups, and that each species had a distinct set or sets of sequences that were amplified in the Y chromosome.

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
