A first-generation map of the turkey genome
Bibliographic record
Abstract
A primary linkage map of the domestic turkey (Meleagris gallopavo) was developed by segregation analysis of genetic markers within a backcross family. This reference family includes 84 offspring from one F1 sire mated to two dams. Genomic DNA was digested using one of five restriction enzymes, and restriction fragment length polymorphisms were detected on Southern blots using probes prepared from 135 random clones isolated from a whole-embryo cDNA library. DNA sequence was subsequently determined for 114 of these cDNA clones. Sequence comparisons were done using BLAST searches of the GenBank database, and redundant sequences were eliminated. High similarity was found between 23% of the turkey sequences and mRNA sequences reported for the chicken. The current map, based on expressed genes, includes 138 loci, encompassing 113 loci arranged into 22 linkage groups and an additional 25 loci that remain unlinked. The average distance between linked markers is 6 cM and the longest linkage group (17 loci) measures 131 cM. The total map distance contained within linkage groups is 651 cM. The present map provides an important framework for future genome mapping in the turkey.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
