Comparative mapping of the region of 11 RPSA pseudogenes in sheep and cattle. The ovine BAC mini-contigs are drawn in part A. Triangles represent BAC end sequences; pointing towards the 3'-end of the BAC clone. Black triangles represent BES from which primers were designed to construct the mini-contigs. White triangles are BES from which it was impossible to design STS-primers. Encircled triangles represent BES that are not annotated. Black squares show overlaps between BES and other BAC clones. Black circles represent genes annotated by PCR. Annotated sequences are shown in a plane map in part B. The position and orientation of the genes present in the syntenic region of Bos taurus are represented with arrows (C).
