Here we compare gene orders on the Sitene latijolia sex chromosomes. On the basis of the deletion mapping results (I I markers and 23 independent Y chromosome deletion lines used), we conclude that a part of the Y chromosome (covering a region corresponding to at least 23.9 cM on the X chromosome) has been inverted. The gradient in silent-site divergence suggests that this inversion took place after the recombination arrest in this region. Because recombination arrest events followed by Y chromosome rearrangements also have been found in the human Y chromosome, this process seems to be a general evolutionary pathway.
