Redneck, a new mutant of the axolotl (Ambystoma mexicanum) likely affects the development of cranial neural crest
Bibliographic record
Abstract
A novel developmental mutant in the Mexican axolotl is described. Designated redneck (rn), the mutant gene is inherited as a simple Mendelian recessive. In homozygotes, rn causes massive haemorrhage in the posterior head, rostrocaudal compression of the craniovisceral skeleton, abnormal differentiation of vertebral cartilage, micrognathia, aglossia, microphthalmia and abnormal hepatic development. Affected larvae become evident at the onset of feeding, and eventually die of starvation. Based on the tissues affected, we propose that rn affects later developmental events in the differentiation and morphogenesis of a subset of cranial neural crest cells. Thus, rn may prove a valuable model system for examining the role of neural crest cells in the development of cranial and endodermal derivatives.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
