Does Haldane's rule speciation within mimetic Poison frogs?

The paper tests Haldane's rule in mimetic poison frogs, finding that hybrids of Ranitomeya fantastica are male-sterile, suggesting XY sex determinism and a role in speciation.

Supergene formation: evidence for recombination suppression among multiple functional loci within inversions.

The paper investigates supergene formation in Heliconius numata, showing chromosomal inversions suppress recombination among multiple loci controlling wing patterns, supporting the hypothesis that supergenes evolve through recombination suppression and subsequent recruitment of adaptive mutations.

Balancing selection at a wing pattern locus is associated with major shifts in genome-wide patterns of diversity and gene flow in a butterfly

The paper examines how balancing selection at a wing pattern locus in butterflies affects genome-wide diversity and gene flow, finding higher diversity and lower geographic structure in polymorphic populations.

The genomics of mimicry: gene expression throughout development provides insights into convergent and divergent phenotypes in a Mullerian mimicry system

The paper investigates the genetic mechanisms of color and pattern variation in poison frogs using genome and gene expression analyses across developmental stages.

Evolution and genetic architecture of disassortative mating at a locus under heterozygote advantage

This study models the evolution of disassortative mating under heterozygote advantage at a locus under balancing selection, showing that genetic architecture and selection regimes influence its emergence.

Mutation accumulation in chromosomal inversions maintains wing pattern polymorphism in a butterfly

The paper shows chromosomal inversions maintain wing pattern polymorphism in butterflies by accumulating recessive mutations that prevent fixation despite ecological advantages.

Genomic architecture and introgression shape a butterfly radiation

The paper uses a low-cost genome assembly strategy to study Heliconius butterfly evolution, finding that introgression, not incomplete lineage sorting, explains most non-canonical genetic histories.
