Data from: A rare exception to Haldane’s rule: Are X chromosomes key to hybrid incompatibilities?



Fertility data from three generations of hybridisation crosses
Numbers of eggs and offspring from three generations of hybridisation crosses (F1, BC1, BC2).The cross types are labelled based on the species X chromosome identity, C= T . commodus, O = T. oceanicus, while hybrid individuals have a prefix either F1 or BC1 and the species identity of their X chromosomes. The first letter represents the maternal species and the second the paternal species identity. (H) indicates an inter-species recombinant X.
