Expression data from testes and abdomen in fertile and sterile introgression males

ABSTRACT: Postmating reproductive isolation is often manifested as hybrid male sterility, for which X-linked genes are over-represented. In contrast, X-linked gene are significantly under-represented among testis-expressing gene.This seeming contradiction may be germane to the X:autosome imbalance hypothesis on hybrid sterility ,in which the X-linked effect is mediated mainly through the misexpression of autosomal genes. We compared gene expression in fertile and sterile males in the hybrids between two Drosophila species. These hybrid males differ only in a small region of the X chromosome containing the OdsH locus of hybrid sterility. Of genes expressed in the testis, autosomal genes were indeed more likely to be misexpressed than X-linked genes under the steriizing action of OdsH. We compared gen
