abstract: Recent studies have uncovered an abundance of non-
neutral cytoplasmic genetic variation within species, which suggests
that we should no longer consider the cytoplasm an idle intermediary
of evolutionary change. Nonneutrality of cytoplasmic genomes is
particularly intriguing, given that these genomes are maternally trans-
mitted. This means that the fate of any given cytoplasmic genetic
mutation is directly tied to its performance when expressed in fe-
males. For this reason, it has been hypothesized that cytoplasmic
genes will coevolve via a sexually antagonistic arms race with the
biparentally transmitted nuclear genes with which they interact. We
assess this prediction, examining the intergenomic contributions to
