title: Male determining factor on chromosome 3 in the mosquito, Culex tritaeniorhynchus.
abstract: Recent experiments indicate that the sex allele M in different populations of Culex tritaeniorhynchus may be present in different linkage groups. In some laboratory wild-type and mutant stocks, M was found to be unlinked to the mutants of linkage group I. Further experiments have demonstrated that in these stocks M is linked to the mutants in linkage group III. Thus, M may be associated with either linkage group I or III. All other markers within a linkage group appear to remain linked to each other and the recombination frequencies among linked markers remain unaltered irrespective of whether or not the M allele was present. The females behave as the homogametic sex in crosses with both types of males. The M allele when associated with linkage group I has been designated M1, when associated with linkage group III it is designated M3. The gene order when M3 is present in linkage group III is Lp-M3-Adh-bw-ae.
