Dear Michgael,

I'm not convinced the model will do the right thing.

Assuming the data is in N sets of 2 traits, try

1 2 1
N 0 0 # N is number of records
2 0 US 1 .5 1 !GFPF !S2==1
Trait.bintrait.sire 2
2 0 US !GP
.05 .06
 0 0 AINV

To check that it is probably working, fix the two covariances to ZERO
and compare the result with separate univariate analyses.
