Variable dosage compensation is associated with female consequences of an X-linked, male-beneficial mutation

Recent theory has suggested that dosage compensation mediates sexual antagonism over X-linked genes. This process relies on the assumption scales phenotypic effects between sexes, which is largely untested. We evaluated this by quantifying transcriptome variation associated with a recently arisen, male-beneficial, mutation across tissues of field cricket Teleogryllus oceanicus , and testing relationship completeness female at level gene expression. Dosage in T. was variable but usually incomplete, such relative expression genes typically greater females. Supporting we found incomplete tended to show female-skewed allele. In gonads, where most strongly female-biased, ovaries-limited were much more likely be than testes-limited genes, supporting view favours feminization X. Our results support expectation sex chromosome substantiating key underlying theoretical role determining dynamics
