Correlation between Barr bodies and neutrophil drumsticks.

There is a marked difference between the frequencies of neutrophil nuclear drumsticks and mucosal cell Barr bodies in any given woman despite the fact that both represent an inactivated X chromosome. We present results of a prospective study carried out on 100 normal Saudi females to assess the statistical correlation between these two variables. We conclude that each is independent of the other. The lack of statistical correlation perhaps relates to maturational and nuclear configuration factors.
