Isolation and inheritance of microsatellite loci in the Dungeness crab (Brachyura: Cancridae: <i>Cancer magister</i>)
Bibliographic record
Abstract
The isolation, PCR amplification, and descriptive statistics of six microsatellite loci are described for the Dungeness crab, Cancer magister. Also reported is the inheritance of these loci in two families obtained from artificial crosses in the laboratory. All six loci conform to expectations under Mendelian inheritance and there is no evidence for linkage between any of the loci. Allelic size ranges for three of the loci are relatively large, ranging from 135-357 bp between the smallest and largest allele detected at that locus. At two of these loci upper allelic drop out (non-amplification of the larger allele in a heterozygous individual) can be problematic for scoring. Results from cross-species amplification in nine congeners are summarized. These loci will be valuable in studies requiring high-resolution genetic markers in Dungeness crabs and related species.
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 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.
