Abstract
Constitutional chromosomal mosaicism is the result of postfertilization mitotic error, the mechanism of which is not fully understood. The distribution of mosaicism in the conceptus depends on the timing, cell lineage(s) involved, cell viability, and chromosome involved. The developmental consequences of mosaicism also are related to its meiotic or somatic type. Meiotic mosaicism often is associated with a more severely adverse effect on the conceptus (see trisomy zygote rescue) due to the presence of uniparental disomy in the embryo/fetus and/or to dysfunction of a trisomic placenta. As mosaicism can be tissue specific, the result of a normal karyotype in cultured lymphocytes does not exclude the presence of mosaicism elsewhere in the conceptus. Mosaicism can best be detected by a combination of traditional cytogenetic analysis with molecular cytogenetic techniques such as comparative genomic hybridization and fluorescence in situ hybridization.

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
