Recovery from hybrid breakdown reveals a complex genetic architecture of mitonuclear incompatibilities

Thiago Lima, Ricardo Pereira, Ronald Burton, Tessa Pierce & Lin Chao
Reproductive isolation is often achieved when genes that are neutral or beneficial in their genomic background become functionally incompatible in a foreign genome, causing inviability, sterility or low fitness in hybrids. Recent studies suggest that mitonuclear interactions are among the initial incompatibilities to evolve at early stages of population divergence across taxa. Yet, the genomic architecture of mitonuclear incompatibilities has rarely been elucidated. We employ an experimental evolution approach starting with low-fitness F2 interpopulation hybrids...
