Certainly from the centrarchid time clock (TEMPO OF HYBRID INVIABILITY IN CENTRARCHID FISHES , BOLNICK AND NEAR ) they are close enough genetically to cross. Uh- oh we may be in over our heads.

Finally, we found that reciprocal crosses often show asymmetrical hybrid viabilities.
We discuss several alternative explanations for this result including possible deleterious cytonuclear interactions. ;\)
