A large number of microclones obtained by microdissection of the mouse X chromosome have been mapped using an interspecific Mus domesticus/Mus spretus cross. Clones displaying close linkage to a number of loci of known phenotype but unknown gene product, such as mdx (X‐linked muscular dystrophy), have been obtained. Over a central 30 cM span of the mouse X chromosome, 17 clones have been mapped and ordered at a sufficient density to contemplate the complete physical mapping of this region that will aid in the isolation of a number of unidentified genes. Some of the mapped microclones detect moderately repetitive sequences that were clustered in several discrete regions of the mouse X chromosome.
