Data from: Persistence of an unusual triple sex chromosome system through allopolyploidization in African clawed frogs (<em>Xenopus</em>, subgenus <em>Silurana</em>)
Bibliographic record
Abstract
This repository includes scripts and genotype files that were used in the associated manuscript. Genotype files (vcf) include Reduced representation genome sequence genotypes for 5 families from four species Whole genome sequence files from 15 X. tropicalis, 1 X. mellotropicalis, 3 X. calcaratus, and 1 X. tropicalis/X. calcaratus hybrid. Scripts include: A Perl script to perform simulations of genetic drift of a three sex chromosome system A Perl script to quantify site patterns for "Analysis 1" described in the manuscript A Perl script to quantify site patterns for "Analysis 2" described in the manuscript A Perl script to generate an artificial allotetraploid from two diploids Two Perl scripts to respectively (i) identify maternal and paternal heterozygous positions from a genotype (vcf) file and (ii) select from an angsd output file the associations of these positions with the phenotypic sex of offspring
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.
