  • To allow for a more accurate comparison of the Dsx proteins, they were divided into three regions: non-sex-specific, female-specific, and male-specific regions. In addition, the OD1 and OD2 domains were also compared. The percentage of similarity refers to the identical plus conservative amino acids. The Dsx proteins of D. melanogaster were used as reference.
