Stk33 gene structure in ostrich. Transcriptomic reads obtained from total RNA of the ostrich cerebellum and testis were mapped back to the genomic reference. Paired-end reads mapping within their paired distance are shown in blue connected by a blue solid line, forward reads in green and reverse reads in red. Broken lines depict split reads. The read coverage is illustrated as a red graph. The stk33 mRNA is annotated as a green arrow, the corresponding coding sequences as yellow arrows. Purple rectangles show GC boxes. All introns are shown with 10 % of their original size
