Fig. 3

Sequence alignments of identified stk33 exons of different birds to African ostrich stk33 mRNA. The ostrich stk33 mRNA is shown as a green arrow, the open reading frame as a yellow arrow. Green lines indicate the mapped exons, red lines indicate inversed exons. Small indels (<5 bp) are shown as blue triangles, large indels (>5 bp) as blue rectangles. Stop codons are illustrated as red asterisks and start codons as a green capital “M”. Black lines depict consensus sequences. The exon 3 region is highlighted by purple broken lines
