Abstract
Sea turtles are wild animals whose embryonic development largely depends on environmental factors. The shell of sea turtles is a novelty among vertebrates and follows a Hox code and axial formula for the group. The hoxb9 gene is a transcription factor involved in the regulation of embryonic development, mainly during neural tube development and plays an important role in shaping the thoracic-lumbar transition of sea turtles. Although it is known that Hox genes are regulated by chromatin modulating proteins, DNA methylation in CpG islands may also contribute to gene regulation. Previous studies have shown a high prevalence of congenital malformations in the olive ridley sea turtle (Lepidochelys olivacea), including Schistosomus Reflexus (SR) syndrome. Here we studied the methylation profiles in the 5’ flanking region of hoxb9 comparing normal and abnormal sea turtle embryos. Our results indicate that methylation of the putative promoter region of hoxb9 in sea turtle embryos occurred, however methylated cytosines showed individual patterns, not directly related to the development of congenital malformations.

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
