Analyses of allelic- and socially-biased gene expression reveal that suppressed recombination causes most of the expression differences in the social supergene, with only few differences due to socially antagonistic selection.

Comprehensive genomic and population genetic analyses of a non-recombining chromosome in white-throated sparrows reveal the actions of purifying selection, positive selection, and balancing selection, expanding our understanding of supergene evolution.

African haplotypes of a meiotic drive supergene in Drosophila melanogaster called Segregation Distorter show signs of a recent selective sweep, reduced recombination, and increased genetic load.

CYP734A50 is a heterostyly gene from primroses that underlies the differences in style length between the two forms by degrading growth-promoting hormones in the short styles.

A complex colour polymorphism which links colour with behavioural and life-history traits is associated with a single gene duplication in male wood tiger moths.

By modulating the intensity of balancing selection at the S-locus, dominance between self-incompatibility alleles shapes the genetic load linked to each allele, creating inbreeding depression in some S-locus homozygotes.

A quantitative trait locus that includes two pheromone receptor genes affects foraging behavior; for one of the genes, the two alleles of the QTL have opposite effects because of distinct sites of expression.

The SARS-CoV-2 main protease specifically cleaves a conserved sequence in the human tRNA modifying enzyme TRMT1, resulting in reduced tRNA binding and the complete loss of TRMT1-mediated tRNA methyltransferase activity.

In the marine midge Clunio marinus, sympatric ecological population divergence with gene flow is based on at least four genetic loci, which partially overlap with large chromosomal inversions.
