Abstract

We compared chromosomal localization of aberration breakpoints and
repetitive DNA clusters (Alu, Hinf repeats and NLRCth1 retro-element copies) in
polytene chromosomes among several Palaearctic population samples of Chironomus
riparius
Mg. from sites polluted with heavy metals. Both breakpoints and repetitive
DNA clusters were significantly more frequent in proximal than in distal chromosomal
regions, and they were found to be significantly associated.
