Genomic Architecture of the Clownfish Hybrid Amphiprion leucokranos.

ABSTRACT: Natural hybridization is increasingly recognized as playing a significant role in species diversification and adaptive evolution. Amphiprion leucokranos, the naturally occurring clownfish hybrid between Amphiprion chrysopterus and Amphiprion sandaracinos, is found within the hybrid zone of the two parental species. Based on whole-genome sequencing of parental and hybrid individuals sampled in Kimbe Bay, Papua New Guinea, we found that most of the hybrids collected were first-generation hybrids, a few were first- and second-generation backcrosses with A. sandaracinos, and the first evidence, to our knowledge, of both an early backcross with A. chrysopterus and a second-generation hybrid in the wild, highlighting the richness and diversity of genomic architectures in this hybrid zone.
