Abstract

fetched live from OpenAlex

As a case study for single-nucleotide polymorphism (SNP) identification in species for which little or no sequence information is available, we investigated several approaches to identifying SNPs in two passerine bird species: pied and collared flycatchers (Ficedula hypoleuca and F. albicollis). All approaches were successful in identifying sequence polymorphism and over 50 candidate SNPs per species were identified from approximately 9.1 kb of sequence. In addition, 17 sites were identified in which the frequency of alternative bases differed by > 50% between species (termed interspecific SNPs). Interestingly, polymorphism of microsatellite/intron loci in the source species appeared to be a positive predictor of nucleotide diversity in homologous flycatcher sequences. The overall nucleotide diversity of flycatchers was 2.3-2.7 x 10(-3), which is approximately 3-6 times higher than observed in recent studies of human SNPs. Higher nucleotide diversity in the avian genome could be due to the relatively older age of flycatcher populations, compared with humans, and/or a higher long-term effective population size.

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.
