estimates of between sex correlations

Dear all,

I would like to fit a model to estimate between sex genetic correlations 
for 3 traits (3 same traits expressed both in males and females) using 
MCMCglmm. My problem is I don't understand how I can manage to fix the 
covariances between male and female traits to 0 for residual variance 
and permanent environment. Could anyone help me with this?

Many thanks in advance

All the best

Celine
