Duplications of genes and larger segments may be mediated by microsatellites. A. Alignment of the Sp185/333 genes and flanking regions. The genes (indicated as colored arrows) and proximal flanking regions between the GA microsatellites (purple triangles) are conserved. (For definitions of distal and proximal flanking regions, see the text and legend for Figure 9.) Conserved sequence between the GAT microsatellites (orange triangles) includes the three D1 genes and the associated intergenic regions. The GAT microsatellites are split into half triangles, except for the one located on the 5' side of D1-b, to show their positions relative to each gene. All of the intergenic sequence between the genes is shown, except for the region between A2 and B8. The fine dotted lines indicate how the sequences fit together on the BAC. The legend shows variations in color that relate to ranges of pairwise diversity scores based on results in B. B. Pairwise sequence diversity relative to the D1-y and D1-g genes. The level of sequence conservation is based on pairwise diversity scores for each of the Sp185/333 genes compared to the D1-y and D1-g genes. Colors in the table correlate to colors in the alignment in A.
