Buccal mucosal cells from 30 males and 20 females were examined for fluorescent bodies in the interphase nuclei. Chromosomal analysis using peripheral blood, stained with quinacrine mustard (QM), was carried out on the 30 males. The calculated lengths of the Y chromosome were found to be related to the percentage of the total fluorescent bodies, both normal (F-body) and atypical (F(a)-body), and also to the proportion of F(a)-bodies present in the interphase nuclei. The long Y individuals had a higher percentage of fluorescent bodies and a higher proportion of F(a)-bodies while the short Y individuals had a lower percentage of fluorescent bodies and a lower proportion of F(a)-bodies.
