Chromosomal aberration tests value
WebChromosome aberrations include changes in chromosome number (gains and losses) and changes in structure (deletions, inversions, and exchanges). Chromosomes can be viewed by standard light microscopy and many of these aberration types can be observed. More recently, a combination of tagged DNA probes and fluorescence microscopy has allowed …
