Retroposed New Genes Out of the X in Drosophila

Although this result suggests that many new genes originated from the X chromosome, it is unclear whether or not this observation is limited to the identified new genes in the group defined by 70% amino acid identity. Thus, we extended a similar analysis (see Methods) to the new retrogenes of 50% or ...
