An Introduction to Chromosomal Aberrations

WebStructural chromosomal aberrations that can be observed and quantified at metaphases are described here. For the detection of chromosomal damage (fragments or whole chromosome) in interphase, the micronucleus test can be used, and a description of this test is also presented. WebChromosomal aberrations in the M1 generation are the first manifestation of the genetic effect of mutagenic treatment. Analysis of the first mitotic cycle after mutagenic treatment and determination of the frequency of chromosomal mutations is a quick test for the evaluation of mutagenic effects.
