The variant red coat colour phenotype of Holstein cattle maps to BTA27
Bibliographic record
Abstract
The variant red phenotype in Holstein cattle is indistinguishable from the traditional e/e recessive red phenotype caused by a mutation in melanocortin 1 receptor, but is inherited as a dominant trait in relation to black. Co-segregation analysis in four half-sib families segregating for variant red was conducted, excluding melanocortin 1 receptor, agouti signalling protein, attractin and melatonin receptor 1A as causative genes. However, variant red co-segregated with markers in a region of BTA27 that includes beta-defensin 103 (DEFB103). Two newly identified microsatellites and 5 SNPs 5' of DEFB103 were used for linkage mapping in four segregating families (LOD = 3.26). One haplotype was inherited in VR cattle in a 6-generation pedigree.

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.
