(a) Genetic maps around the sex-determining (SD) locus. Numbers above the genetic map indicate the recombination events in 1,571 progeny. The SD locus was mapped within a genetic interval between two markers (IMBY28J06 and F38_01F). (b,c) BAC contigs and physical maps of the Y and X chromosomes in O. dancena (b), and a physical map of the homologous sequence (6,885,000–7,080,000 bp) on chromosome 10 in O. latipes (c). Blue and purple lines indicate BAC clones; blue, purple and green boxes indicate genes; and arrows indicate the direction of transcription. Orthologous genes are connected by grey shading.
