Map position of phosphoglucomutase (Pgm) locus on autosome IV of house fly (Diptera: Muscidae).

We determined the map position of phosphoglucomutase (Pgm) locus on autosome IV of housefly, Musca domestica L. (Diptera: Muscidae), by using three and five point linkage test crosses. Test strains had visible mutant markers (car, bwb, cyw, and aabys). We analyzed 1738 offspring in total from two groups of single-pair matings by electrophoresis. Here, we report the linkage of Pgm locus to autosome IV loci curly wing (cyw) and yellow eyes (ye) with recombination frequency of 16.9 and 1.1%, respectively. We combined the distances calculated from this study and the previously published data. An updated linkage map of the M. domestica L. Autosome IV was drawn based on combined data in terms of real map units obtained from the mapping function.
