Abstract

fetched live from OpenAlex

Atlantic salmon, Salmo salar, from the Chaleur-Bay district in eastern Canada has the same chromosome number, 2n = 58, as Atlantic salmon from Sweden. Hybrids between salmon from Chaleur and the river Lule in Sweden also have the chromosome number 2n = 58 and form multivalents and bivalents of the same type and proportion as in Scandinavian salmon. Hence, salmon from Canada and Scandinavia are presumed to have the same origin and, therefore, may be utilized in intraspecific crosses in order to improve the different strains used for breeding on both sides of the Atlantic. Hybrids between Atlantic salmon and sea trout have chromosome numbers around 2n = 69. In the meiosis rodshaped units only, and no rings, are formed together with a high number of univalents. Thus, apparently, reciprocal translocations have caused the occurrence of multivalents in the meiosis of salmon and not autopolyploidy as was earlier assumed.

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 imitation

Not 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.
