Abstract

Prior to the advent of whole-chromosome painting, it was universally assumed that virtually all radiation-induced exchanges represented a simple rejoining between pairs of chromosome breaks. It is now known that a substantial proportion of such exchanges are actually complex, meaning that they involve the interaction of three (or more) breaks distributed among two (or more) chromosomes. The purpose of this review is to discuss some of the implications of aberration analysis using whole-chromosome painting, with emphasis given to newer combinatorial painting schemes that allow for the unambiguous identification of all homologous chromosome pairs. Such analysis requires reconsideration of how resulting information is to be handled for the purposes of tabulating and communicating raw data, quantifying aberration yields, and presenting experimental results in a cogent manner. Facilitating these objectives requires the introduction of certain concepts and terminologies that have no counterpart in conventional cytogenetic analyses.
