Extended Data Fig. 4: Sequence contexts of the sex determining regions in Chr25 of A. chinensis and A. polygama.

a-b, close-up of the Y-haplotype region of Chr25 in A. chinensis. a, An approximately 1.3 Mb region (putative MSY) exhibited mostly male-specific coverage of genomic reads. b, Synteny between Y- and X-haplotypes. Green bands indicate predicted genes. c, close-up view of the Chr25 Y-haplotype region in A. polygama. The MSY corresponds to a ~1.1 Mb region.
