A Novel Supergene Controls Queen Size and Colony Social Organization in the Ant Myrmica ruginodis.
Article in Molecular biology and evolution, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Large independently evolved supergenes control colony social organization and queen reproductive strategies in several ant lineages. Their independent origins, as well as the similarities of the associated phenotypes, make ant supergenes a promising system for studying the parallel evolution of genome organization and adaptability. However, the genetic basis of differences in social organization and queen phenotypes remains unknown in many ant species, limiting the potential power of this system for comparative studies. We investigated the genetic basis of colony social organization in the queen-size dimorphic ant Myrmica ruginodis by sampling 95 queens from 31 colonies in southern Finland. Whole-genome sequencing revealed a novel 9 Mb supergene associated with both queen size and social organization. Queens homozygous for the AA haplotype were larger and found only in single-queen colonies, while queens in multiple-queen colonies were smaller and carried only AB and BB genotypes. This supergene is not homologous to previously identified supergenes in ants, suggesting it arose through a distinct evolutionary pathway.
