[R-sig-ME] indirect maternal genetic effects

Hello everyone,
I am trying to model direct genetic effects and indirect maternal
genetic effects on infant survival, using MCMCglmm. From what I know and
understood from the ASReml code on how to model this, I should include
the identity of my focal individual ("animal") to estimate the direct
genetic effect, include the identity of his mother ("dam") to estimate
the maternal environment effect and then add another variable which
should represent the genetic effect of the mother on the focal
individual. I assumed that I should add the same "dam" variable but give
it its own incidence matrix through ginverse(), but I am not sure about
this. I would appreciate some help on how to code this relationship.
Thank you
