This study examines dosage compensation mechanisms on ancestral and neo-Z chromosomes in butterflies, revealing varied gene expression patterns and highlighting the role of evolutionary history and gene function in shaping these mechanisms.

From 338 beetle genomes, eight ancestral linkage groups were inferred; rearrangement rates vary widely, peaking in major radiations, and the X chromosome dates to Holometabola's ancestor.

This study examines two Neotropical butterfly radiations, revealing high rates of hybridization and chromosomal rearrangements as drivers of diversification.

The paper identifies genomic regions linked to hybrid inviability in butterflies by comparing allele frequencies in surviving and non-surviving F2 hybrids, showing these regions are in fast-evolving, low-recombination areas with chromosome fusions.

This study identifies gene expression changes in painted lady butterflies in response to environmental cues, highlighting pathways involved in migration and reproduction.

This study investigates recombination rate variation in butterflies, finding bimodal patterns in large chromosomes, lower rates in subtelomeres, and associations with transposable elements and gene activity.

This study develops a high-density linkage map and annotates the genome of the painted lady butterfly, revealing gene family expansions and recombination rate variation linked to genomic features and lifestyle adaptations.
