Fig. 1.Organization of eight bz haplotypes. Each haplotype is identified by the name of the genetic line, followed by the size of the cloned NotI fragment, in parentheses. The locations of the NotI sites at the proximal and distal ends are marked by Ns on the left and right, respectively. Genes are shown as pentagons pointing in the direction of transcription; exons are in bronze and introns in yellow. There are eight genes in the region: bz, stc1, rpl35A, tac6058, hypro1, znf, tac7077, and uce2 (21). The same symbols are used for gene fragments carried by helitrons (Hels), which are represented as bidirectional arrows below the line for each haplotype. The vacant sites for HelA and HelB in each haplotype are provided as reference points and marked with short vertical strokes. Dashed lines represent deletions. Retrotransposons are indicated by solid triangles of different colors. DNA transposons and TAFTs, which are probably also DNA transposons, are indicated by open triangles in red and orange, respectively. Small insertions are indicated in light blue and are numbered as indicated in Table 3. Only the genes have been drawn to scale.
