Alignment of Ygua and Ymac haplotypes to Xiphophorus Chromosome 8. A 3.5 Mb inversion distinguishes X. hellerii and X. maculatus. The position of the long contig Gua_tig00000294 that spans the inversion of X. maculatus Chr 8 is indicated at the top. The position of a short proximal sequence of the guppy Y also conforms to X. hellerii Chr 8, whereas it is translocated to the chromosome end in X. maculatus. Ygua and Ymac conform to one another and to X. hellerii Chr 8, with most divergence seen from 23 Mb to the end of guppy Y haplotypes.
