The report of the bovine X chromosome (BTAX) workshop is presented. Five laboratories contributed 39,067 informative meioses from 92 loci. Fourteen loci typed by at least two laboratories were used to construct consensus linkage maps. The consensus map of BTAX was 159.3 cM, and the map of BTAY was 20.4 cM. The sex-averaged consensus map of the pseudo-autosomal region (PAR) covered 20.1 cM. The comprehensive maps were constructed using 90 o the 92 loci. The lengths of the BTAX and BTAY maps were 155.8 cM and 28.8 cM, respectively; while the sex-averaged comprehensive map of the PAR was 25.8 cM. Average distance between loci for BTAX was 1.73 cM.
