title: Construction of a high-resolution genetic map encompassing the hotfoot locus.
abstract: Hotfoot (ho) is a mutation affecting posture and movement. We report a new allele associated with the insertion of a transgene and its high-resolution mapping. Analysis of the transgene revealed that two complete and two truncated copies are inserted at the ho locus. The ho locus cosegregated with D6Mit299 in 702 meioses and is confined to a 1.1-cM region between the markers D6Mit122 and D6Mit174. If the order and distances between markers are consistent with previously published mapping data, the position of the ho locus must be revised and placed approximately 30 cM from the centromere. This high-resolution genetic map is the first step towards the positional cloning of the ho mutation.
