Abstract
The locus of the genestriated, Str, on the mouse X-chromosome, was previously reported to be on the side of tabby (Ta) away from bent-tail (Bn). Results given in the present paper show this report to have been incorrect, and that the order of loci isBn-Str-Ta-(Mo-Blo). In addition, the position of the translocation break in Searle's translocation (T1GH) has been confirmed, the order of loci with respect to T16H beingBn-T16H break-Ta-Blo.
