Our experimental approach was to induce sister chromatid exchange in a ring chromosome to generate a dicentric chromosome with a double chromatid bridge. In the following cell division, the ... WebJul 13, 2024 · Drosophila start life as fertilized eggs that develop into embryos and then become larvae. There are three larval stages where larvae molt in order to continue growing in the next larval stage. After the third larval stage, Drosophila will pupate, which takes about one week from the initial deposition of the fertilized egg by its mother.
