| Here we study thermal coadaptation in Caenorhabditis elegans. |
| The coadaptation theory requires fitness interactions between mothers and offspring. |
| These shifting patterns of coadaptation are further shaped by the geographic structure of most species. |
| One example of the biological importance of intergenomic coadaptation is the evidence that mtDNA interaction with the nuclear genome modifies cognition in mice. |
| In spite of its apparent simplicity, this idea has been difficult to evaluate empirically, and coadaptation of host and parasite traits is usually assumed rather than demonstrated. |
| The coadaptation model relies on suppressed recombination in arrangement heterozygotes, but it also assumes equal transmission of homologous chromosomes during meiosis. |
