Frequencies of chromosome aberrations in a control population determined by G banding

Control data on chromosome aberration frequencies determined by G banding f rom several studies undertaken in this laboratory have been re-analysed in relation to age and smoking. The combined study group comprised a total of 162 men (90 non-smokers and 72 smokers) with ages ranging from 20 to 72 yea rs. For the group as a whole, significant increases were observed in transl ocations and all symmetrical exchanges with increasing age and also when sm okers were compared with non-smokers.
