Re: Maternal Genetic effects in ASReml-R

Dear ASReml-R users,

Just to summarize private interchange between the developers and Jarrod,

1) Currently the link() syntax in ASReml-R does not accomodate
covariance between say
direct and maternal effects.

2) To properly fit say maternal genetic and maternal environment
(ignoring direct maternal covariance)
   you need to use the ide() wrapper as well as the ped() wrapper.
i.e.
    ~ ped(animal,var=T) + ped(dam,var=T) + ide(dam,var=T),
     ginverse=list(animal=Gped, dam=Gped)

May Jesus Christ be gracious to you in 2008,

Arthur Gilmour, His servant .
