Abstract:

These conclusions are based on the results obtained in the study of the phenotype of pochromosomes with the identification of chromosomal rearrangements in normal conditions and pollutthe environment of polyten chromosomes from the larvae of one of the most important species of d Chironomus plumosus. The number of these restructurations is far bigger and the restructurations more complex at the recolted larvae from the zones considered critic under the aspect of pollution county of Arad, as opposed to those recolted from the zones considered unpolluted from the county.Multiple types of chromosomal restructurations were evidenced, among which inversions, delettranslocations, desinapsies, ectopic pairings, and also the existence od the aneuploids represented thromonosomia and trisomia

Keywords:

polytene chromosomes; Chironomus plumosus; pollution; chromosomes restructurations; inversions; deletions; translocations; monosomia and trisomia.
