New paper out now in #ProcB @royalsocietypublishing.org We explored how sex loss shapes gene expression patterns by comparing sexual & asexual aphid lineages 🧬🪲 🔑 #SexualAntagonism #Parthenogenesis #Asexuality #Transcriptomics #SexBiasedExpression #SexualDimorphism 🔗 doi.org/10.1098/rspb...

The release of sexual conflict after sex loss is associated with evolutionary changes in gene expression | Proceedings of the Royal Society B: Biological Sciences

Sexual conflict can arise because males and females, while sharing most of their genome, can have different phenotypic optima. Sexually dimorphic gene expression may help reduce conflict, but the expr...
