Structure of BCAR1 gene in channel catfish. The BCAR1 genes contain 8 exons, and four transcript isoforms of BCAR1 gene exist. Isoform 2 and isoform 4 start in exon 1 and contain exons 3–8, but have slightly different splicing sites from each other. Isoforms 1 and 3 begin in exon 2 and contain exons 3–8 but slightly different splicing sites. The red lines indicate the position and sequences of the male-specific transcript and that sequence from the YY genome is shown at the bottom
