Abstract

fetched live from OpenAlex

Gynogenetic organisms are asexual females of one species that require sperm from males of another species to initiate reproduction (but except in rare instances of ‘paternal leakage’, those sperm do not contribute to the genetic make-up of the gynogens’ offspring). Gynogenetic organisms seem to combine disadvantages of both sexual and asexual reproductive strategies (e.g., mating costs, reduced genetic diversity). We borrowed logic from the Red Queen Hypothesis (RQH) to help explain the persistence of gynogenetic species in nature, which is a paradox. The RQH is the most oft-cited explanation for the maintenance of sex. It states that evolving enemies generate a constantly changing environment, which provides the conditions that make sex advantageous. Under this scenario, asexual organisms cannot evolve fast enough to ‘keep up’ with co-evolving parasites and disease causing organisms, and ultimately show reduced fitness compared to sexual individuals. The RQH tends to view asexuality generally, ignoring important nuance in nature like gynogenetic species in mixed assemblages with closely related sexual species. We outline tests of the argument that sperm dependency prevents asexual gynogens from outcompeting sexuals in mixed species assemblages and that this further allows gynogens to escape evolving enemies.

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.
