Table 1 Splice donors and acceptors of the Cxqdsx gene. Coding (exon) sequences are in uppercase text, while the splice donor/acceptor and succeeding/preceeding 12 nucleotides, respectively, are in lowercase. “Exon 4ex” denotes the alternate downstream splice donor of exon 4. Asterisk indicates the splice acceptor site deviates significantly from the genomic mean of 8.58 +/− 1.39 SE (see Methods)

From: Characterization of the doublesex gene within the Culex pipiens complex suggests regulatory plasticity at the base of the mosquito sex determination cascade
