Abstract

Genetic analysis of backcross progeny from previously characterized rat inbred strains revealed that the biochemical marker Lap-1 is localized in linkage group I (LG I). Lap-1 codes for leucine arylaminopeptidase (EC 3.4.11). The distances of Lap-1 to c, RT6, and Hbb, based on recombination frequencies, are 3.1±1.5, 8.3±4.0, and 11.4±2.8 cM, respectively. Acon-1 codes for aconitase (EC 4.2.1.3). The calculated distances of Acon-1 to c and Hbb are 30.1±5.0 and 36.1±5.3 cM, respectively. This suggests that Acon-1 is also in LG I, but the observed high frequency of double crossovers requires further confirmation of this linkage. Ahd-2, Es-6, and Gdc-1 are linked neither to markers of LG I nor to one another.
