The Sp185/333 genes on 7096 have four different element patterns. The genes are aligned according to the repeat-based alignment . The genes have two exons and a single intron that is shown as a white box (not to scale). The first exon encodes the leader (L). The Greek letters indicate the intron type based on sequence analysis . The second exon has large gaps (horizontal lines) inserted to optimize the alignment, which define blocks of sequence called elements (gray and colored boxes). The consensus of all possible elements is shown at the bottom. Variations in the presence or absence of elements defines element patterns (A2 γ, B8 β, D1 α, and E2 δ, which are abbreviated according to ). Elements that correlate with each of the six types of repeats are shown in different colors (type 1 in red; type 2 in blue; type 3 in green; type 4 in yellow; type 5 in purple; type 6 in orange; ). The figure is modified from .
