Fig. 3. Exon/intron organization of AgdsxF and AgdsxM and
comparison with the female and male transcripts of Dmdsx. Exons are
shown as boxes, where black boxes represent untranslated regions and open
boxes represent coding regions. The OD1 domain is indicated by diagonal
hatched boxes, and the non-sex-specific region of the OD2 domain by stippled
boxes. Male- and female-specific regions of the OD2 domains are indicated by
vertical and horizontal hatched boxes, respectively. In Agdsx, a
male-specific region of the OD2 could not be identified. Introns and exons are
numbered according to the sequence of the female transcripts. The exon/intron
boundary between the last common exon and the sex-specific regions is
conserved between Dmdsx and Agdsx. Vertical arrows indicate
the region where the dsxREs and PREs are found. Introns are not shown
to scale.
