D relationship matrix
Hi Craig, I'm not aware of anything in R but I believe Ignacy Misztal's fotran routines http://nce.ads.uga.edu/~ignacy/newprograms.html or Per Madsen and Just Jensen's DMU package http://www.dmu.agrsci.dk/ will calculate D and presumably D-1. Hoeschele & van Raden (J. Dairy Science 74:557-569) provide a recursive algorithm for D-1 in the absence of inbreeding and this may not be that hard to implement. Cheers, Jarrod

Hi Folks
just wonderinf if any one has some code to write the D realtionship
matrix (or inverse) for an outbreed population with no inbreeding
that I could use?
Thanks for your help
