Fig. 8: C. hominivorax doublesex gene organization and sex-specific transcripts.

a The Chdsx gene consists of four exons common to both sexes (gray or open boxes), one female-specific exon (red box) and three male-specific exons. Introns are shown with a black line with a gap indicating the intron is larger than shown. Otherwise all exons and introns are drawn to scale. Translation start and stop codons are indicated. Female and male splicing patterns are shown above and below the gene respectively. The location of the predicted TRA/TRA2 sites is indicated above the 3′UTR of the female-specific exon. b The sequences of the nine predicted TRA/TRA2 sites that are at a least a 13 out of 14 match to the consensus sequence 5′-CAACAATCAACATA-3′ are shown.
