Abstract excerpt

In the present work, we have asked whether a group of 13 essential genes mapping to the heterochromatin of Drosophila melanogaster chromosome 2 are mutable following transposition of the I factor during I-R hybrid dysgenesis. We found that the frequency of lethal events mapping to chromosome 2 he...
