[The characteristics of the chromosomal level of variability in mice]

The analysis of the order of chromosome involving to interchromosome associations by the type of Robertsonian translocation (RB) in 28 cell populations in relation with three factors: their origin from different mouse lines (CBA/Ca, C3H/He, C57BL/6, BALB/c), direction of cytodifferentiation (fibroblasts and leucocytes) and the stage of its disruption (minimal, maximal and medial tumorigenicity) was carried out. The influence of all three factors on the frequencies of individual chromosome involving in RB was revealed.
