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

This study shows that heterozygote advantage can maintain over 100 alleles at MHC loci if pathogens are lethal without immune defense and their impact depends on host condition.

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.
