Results of the phylogenetic analyses using OVOG were compared to those obtained using the mitochondrial cytochrome b (cytb) gene to determine the phylogenetic utility of OVOG. OVOG appeared to have strong phylogenetic signal for reconstructing relationships among genera and families, and the only ...

Polyploidization is one of the few mechanisms that can produce instantaneous speciation. Among animals, gray tree frogs (Hyla versicolor complex) have been the source of considerable debate regarding speciation by polyploidization. Molecular evidence and advertisement calls indicate that tetraploid gray tree frogs originated multiple times from extant diploid gray tree frogs and two lineages of...
