Neofunctionalization of a Noncoding Portion of a DNA Transposon in the Coding Region of the Chimerical Sex-Determining Gene dm-W in Xenopus Frogs
Abstract
Most vertebrate sex-determining genes (SDGs) emerge as neofunctionalized genes through duplication and/or mutation of ancestral genes that are involved with sexual differentiation. We previously demonstrated dm-W to be the SDG in the African clawed frog Xenopus laevis and found that a portion of this gene emerged from the masculinization gene dmrt1 after allotetraploidization by interspecific hybridization between two ancestral species around …
