The prominent role of ectopic pairing in the toroidal conformation of Drosophila polytene chromosome bands.
An examination of the polytene chromosomes of some Drosophila species from the montium subgroup, namely, D. auraria, D. serrata, D. jambulina and D. bicornuta, revealed an intimate relationship between ectopic pairing and the toroidal conformation of the polytene chromosome bands. The possible significance of these events is discussed.
