Abstract
Plasmids containing Drosophila virilis DNA (pDv118, pDv719, pDv714 and pDv117), characterized and localized on D. virilis chromosomes in Riede et al. (1983) were localized by in situ hybridization with polytene chromosomes of the hybrids D. virilis × D. lummei, D. virilis × D. novamexicana, and D. virilis × D. lacicola. The degree of somatic pairing was determined by comparing the four plasmids in the three hybrids. We found that somatic pairing in the polytene chromosomes decreased with decreasing DNA homology of the bands. — Additional cytological studies indicated that (1) each band can pair independently of its neighboring bands, (2) visible structural differences between bands have no influence on pairing of the surrounding chromosome region, (3) heteromorphic bands can pair by themselves, and (4) inversions of chromosome regions disturb the somatic pairing process but are not the primary cause for nonpairing in hybrids.
