Genetic Assessment of Fertile F1 Hybrids between Two Hercules Beetles, Dynastes maya Hardy and D. grantii Horn (Scarabaeidae).

ABSTRACT: Although hybridization may complicate taxonomic practices, it can be common between animal species. Animal hybridization not only can help with generating phenotypic and species diversity in nature, but also with understanding the genetic and genomic basis of phenotypic evolution in the laboratory. We assessed the genetic composition of captive bred F1 hybrids between two Hercules beetle species using mitochondrial CO1 and nuclear loci from a double-digest restriction-site associated DNA sequencing (ddRADseq) library. We showed that the F1 hybrids were genetically clustered with samples from the maternal species, D. grantii, based on CO1 data. Nuclear genome data, on the other hand, clearly showed that the F1 individuals were genetically intermediate between D. maya
