Анализ генетического полиморфизма базидиомицета Chondrostereum рurpureum по RAPD-маркерам
Bibliographic record
Abstract
Fifteen samples (fruitbody tissue isolates) of Ch. purpureum, collected throughout Minsk City, were subjected to RAPD-PCR with 3 primers of OPA series and 7 priers of Pseries. Each sample/prim er pair produced unique fingerprint, which permitted to distinguish 10 different genotypes from 10 separate substratum units. The analysis included 64 RAPD loci, obtained with 5 primers; 14% of the loci was monomorphic; 34% of polymorphic loci had the frequency 0.5 and more. Small spatial clusters of individuals (subpopulations) bore 70-75% of the bands, involved in the analysis; 39-47% of the all studied loci only were polymorphic within these subpopulations. Dice similarity coefficients between the genotypes were 0.58-0.83 in the studied sample, which was generally in agreement with the data on Ch. purpureum in Canada. The genetic variation of Ch. purpureum in Minsk City was lower, than among individuals of ecologically close basidiomycete Stereum hirsutum,collected from the same area and tested by the same method.

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.
