Abstract: | Summary Males of three inbred lines ofDrosophila melanogaster were heat-shocked 90 min at 37°C. The progenies from treated and untreated males mated with untreated females of the same
line were checked for their chromosomal insertion patterns of various mobile elements by either in situ hybridization or Southern
blots. No modification in the pattern of insertion of the elements studied was observed after heat treatment. Hence, heating
males of our inbred lines did not mobilize mobile elements, contrary to recent reports on other lines ofDrosophila melanogaster. |
