Abstract
Two cases of spontaneous transpositions of MDG1, MDG3, and copia retrotransposons were detected in Drosophila melanogaster lines derived from the nonadaptive NA line and marked by recessive visible mutations. The transpositions were accompanied by a dramatic increase in individual fitness (competitive success). In independent instances of MDG1 transpositions, the location patterns of new sites were similar. These results confirm the existence of adaptive transpositions that were demonstrated earlier for the NA line that carried no visible markers.
