Abstract

fetched live from OpenAlex

Microsatellite markers for Atlantic cod (Gadus morhua) were identified from a collection of 30 630 expressed sequence tags. Primers were designed for 395 microsatellites and 155 were successfully amplified. Allele number varied from 1 to 26 (average 6.34). Average observed and expected heterozygosities were 0.50 and 0.54, respectively. A subset of 105 microsatellites tested for Mendelian segregation showed no significant distortion of segregation when correcting for multiple tests. Null alleles were detected at four loci. Significant blastx matches were found for 23 loci. These microsatellites will be used to create a linkage map to enhance genetic selection in commercial cod breeding.

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.

Not 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.
