Abstract

fetched live from OpenAlex

Sry, a single-copy gene on the Y-chromosome, triggers the fetal gonad to begin testis differentiation in mammals. On the other hand, mutation or absence of Sry results in ovary differentiation and the female phenotype. However, cases of XY sex reversal in the presence of wild-type Sry exist in mice and man. One such example is the B6-Y(TIR) mouse, whose autosomes and X-chromosome are from the C57BL/6J mouse (an inbred strain of Mus musculus molossinus), whereas the Y-chromosome is from a Mus musculus domesticus mouse originating in Tirano, Italy. The B6-Y(TIR) mouse never develops normal testes and instead develops ovaries or ovotestes in fetal life. It has been suggested that low levels of Sry transcription may account for the aberrant testis differentiation in the B6-Y(TIR) mouse. In this study, however, we observed relatively low levels of Sry transcripts not only in B6-Y(TIR) but also in B6 mice, which develop normal testes. We conclude that low dosage of Sry transcripts cannot be the sole cause of sex reversal in the B6-Y(TIR) gonad.

Not 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.
