Experimental evolution unveils a role for structural variants and sex-specificity in the genetic architecture of lifespan

This study uses experimental evolution in seed beetles to show that structural variants and sex-specific genetic factors influence lifespan evolution.

Sex-specific dominance maintains multilocus polymorphism and can resolve sexual conflict

This study shows that sex-specific dominance can maintain genetic polymorphism across multiple loci and reduce within-sex phenotypic variance, resolving sexual conflict.

Sign epistasis extends the effects of balancing selection on genetic diversity

The paper models how balancing selection can extend its diversity-promoting effects to loci with sign epistasis, showing dominance and recombination rate are key factors.

The coevolution of sex-specific dominance and allelic diversity at sexually antagonistic loci

The paper models how sex-specific dominance and allelic diversity coevolve at sexually antagonistic loci, showing that weak selection can lead to polyallelic polymorphism and reduced segregation load.
