Abstract
Linkage group I is defined as the loci on the differential part of the X-chromosome of adult G. m. morsitans Westwood. Three loci are known and their order on the X-chromosome was demonstrated as ocra (body color), salmon (eye color), and Apk (arginine phosphokinase, E.C. 2.7.3.3) with 38 map units separating the first 2 loci and 32-41 separating the 2nd 2. This region of the X-chromosome does not contain the chromosomal inversion known to occur in the Handeni line of G. m. morsitans. Linkage group II is defined as the autosome carrying the locus Xo (xanthine oxidase, E.C. 1.2.3.2), and it is demonstrated to also carry the loci Ao (aldehyde oxidase, E.C. 1.2.3.1) and Odh (octanol dehydrogenase, E.C. 1.1.1.73). Ao and Odh are within 0.36 map units of each other and were not separated by recombination; this pair of loci occur about 48 map units from Xo. During mapping experiments, no evidence for genetical recombination was found in male G. m. morsitans.
