The first tests of the possible influence of inbreeding on recombination were performed with lines which had been kept in the laboratory for decades. As the results agreed fairly well with the standard map of the X‐chromosome a new set of tests were carried out, using the F 2 offspring of a captured wild female, thereby minimizing the effect of laboratory culturing. After brother x sister mating her offspring for 40 generations, a new set of tests were performed. In both groups of tests the same marker genes were used. (The marker genes had been induced in an inbred laboratory line.) The results both prior to and after inbreeding were fairly congruent. This indicates that inbreeding per se has no influence on the recombination frequency. There is, however, a random inclusion of alleles which do affect recombination, though only in specific regions of the X‐chromosome.
