Microsatellite-polymorphism and association with production traits in Japanese quails
Bibliographic record
Abstract
The genetic polymorphism in 40 unrelated Japanese quails belonging to two strains (Black and White) was investigated using five microsatellite loci (GUJ0008, GUJ0034, GUJ0041, GUJ0056 and GUJ0070), which was then associated with body weight at 5 weeks of age trait. The genomic DNA was isolated from the peripheral blood samples collected aseptically from the birds. The PCR products for different microsatellite loci were resolved on 3.5% Metaphor agarose against 100 bp plus DNA ladder (Fermentas, Canada) and manually scored for the band patterns. The Chi-square test indicated that the loci might be under the influence of forces like selection, migration, mutation, etc. as all locus-strain combination deviated from Hardy-Weinberg equilibrium. The number of alleles in the different microsatellite loci studied varied from 6 to10, indicating a high degree of polymorphism. The PIC value was the highest for locus GUJ0070 for white plumage (0.698) and locus GUJ0034 for black plumage (0.768). Specific alleles were found to be private to either of the strain for the loci studied except for GUJ0070 locus. The GUJ0034 locus had a significant effect on the body weight at 5 weeks of age (BWT5) (p<0.05). The genotypic value of BWT5 was found to be the highest in genotype “FD” and the lowest in genotype “BA”. The microsatellite may be used in a separate independent sample of Japanese quails for selecting the birds at 5 weeks of age for higher body weight, before attaining sexual maturity.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
