TOWARD A PHYSICAL MAP OF AEDES-AEGYPTI

Labelled recombinant cosmids were used as in situ hybridization probes to Aedes aegypti metaphase chromosomes, The cosmid probes yielded paired signals, one on each arm of sister chromatids, and they were ordered along the three chromosomes, in total, thirty-seven different probes were mapped to the three chromosomes of Ae. aegypti (2n = 6): twenty-eight to chromosome 1, six to chromosome 2, and six to chromosome 3. These results represent an initial stage in the generation of a physical map of the Ae. aegypti genome.
