Figure 6

Repeat-based alignment of the 185/333 genes. The alignment was optimized for repeats and 27 elements (colored boxes) were defined. Gaps due to missing elements are indicated by horizontal black lines. There are 17 different exon element patterns, which, when combined with the intron types (Figure 3), form a total of 21 unique gene patterns. The frequency (Freq) of patterns indicates how often the pattern was identified. The source animal for each pattern is indicated by the presence of a colored dot as in Figure 2. The subtype of element Er10 (which corresponds to Ex15, Figure 2A) is indicated by the letter in the box. Intron patterns are unaffected by this alignment because they do not have repeats; their designation corresponds to that shown in Figure 3.
