Comparative analysis of microsatellite loci in chicken and turkey
Bibliographic record
Abstract
Cross-species amplification of 520 chicken microsatellite markers was tested by polymerase chain reaction with genomic DNA of the turkey (Meleagris gallopavo). Each primer pair was tested at six different combinations of annealing temperature and MgCl2 concentration. A total of 280 (54%) of the primer pairs produced amplification products. The majority of these products were similar, if not identical in size to those expected based on the fragment sizes of the corresponding chicken loci. Structure of the dinucleotide repeat and flanking sequences was examined for 13 turkey fragments (amplified with chicken primers) and 5 chicken fragments (amplified with turkey primers). Sequence analysis found a wide array of mutations between species in addition to differences in repeat length. To estimate the usefulness of the amplified loci for genetic mapping in the turkey, allelic polymorphism was determined for 57 of the 280 amplified loci. A total of 20 of 57 markers (35%) were polymorphic with an average of 1.4 alleles per locus. The results of this study suggest that approximately 20% of the chicken microsatellite markers will be useful for mapping the turkey genome.

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.
