SNP allele frequency spanning the male specific region in male and female fish. B allele frequency (BAF) is shown for 163 SNP distributed across the 20 Kb contig containing the sdY gene. BAF represents the number of reads that carry the B allele as a proportion of the total number of reads observed per SNP within a single animal. Homozygous genotypes therefore take values of 0 or 1. BAF is plotted separately from six female (A) and six male fish (B).
