Abstract:
:The location of DNA fragments representing mobile dispersed genes (MDG) in salivary gland and midgut polytene chromosomes was compared by means of in situ hybridization. In the Drosophila stock under study the average number of hybridization sites in the polytene chromosomes of one nucleus was 20 for MDG-1 and 10 for MDG-3. The total numbers of hybridization sites and their relative positions proved to be same in the polytene chromosomes of the two tissues. These results support the idea of a stable location of the mobile dispersed genes in the course of ontogenesis.
