Evaluating evidence of mitonuclear incompatibilities with the sex chromosomes in an avian hybrid zone

Daniel Hooper, Kelsie A Lopez, Callum S McDiarmid, Simon Griffith & Irby Lovette
The exploration of hybrid zones and the intergenomic conflicts exposed through hybridization provide windows into the processes of divergence and speciation. Sex chromosomes and mitonuclear incompatibilities have strong associations with the genetics of hybrid dysfunction. In ZW sex-determining systems, maternal co-inheritance of the mitochondrial and W chromosomes immediately exposes incompatibilities between these maternal contributions of one species and the Z chromosome of another. We analyze mitochondrial and Z chromosome admixture in the long-tailed finch (Poephila...
