Using plant pedigrees...

In using ASREML for sugarcane (where lines are fixed clones), we find
that it would be more convenient to be able to use a GIV file, rather
than a PEDIGREE file when trying to formulate the model for estimation
of breeding values (another reason for this is that lines can be used
either as males or females).

So, given a pedigree file, ASREML can apparently deal with clones by
using 'ide' in the model:

Y ~ !f something !r ide(Clone)

I would like to know if, when I output the calculated GIV file for this
run (using !GIV), the matrix of distances will also assume that the
pedigree is of clones? Or will the GIV file be the same as if I had used
a model like this:

Y ~ !f something !r giv(Clone)

Thanks,
